TCS PATTERN & INTERVIEW
TCS conducted campus interviews for our college students . It follows 3 or 4 stages based on panel you were sent through the Selection Procedure. The stages may be
1. Written Test
common for everyone except for top 5 in circuit branches like ECE, CSE, IT, EEE, EIE
Top 5 students in above mentioned branches can attend direct TECHNICAL INTERVIEW
written test was held on 27th of November.
The test was of duration 1hour 20 min containing 35 questions with 1 mark for every positive response and one-third negative marks for wrong option chosen
There will be different slots for the written test.
The questions will be quantative aptitude only with a mix of logical reasoning and sometimes very lengthy questions but simple logic
if you know the concept there will be sufficient time for the questions
The better way deal the written test is to solve as many as previous papers possible. Form a study group and discuss the problems of previous papers throughly and know the concept in them. This is just enough to crack written exam why because TCS gives repeated questions with just change in numbers. I give 100% assurance if you this method to crack the written exam.
I wrote my written test in the opening slot as per my TCS registration number. It is an online exam. Be careful with the controls (like button) and dont submit your test in a hurry manner as you may be disqualified. I answered questions randomly and tried to maximize my score with accuracy. After a complete overlook i picked one by one carefully and then answered them. Finally as the time is up i answered 33 questions and i have doubt on one question and for the other when i tried to attemped to it my time was over.
The results were declared around 8pm. I got on to next round. Totally 383 students cleared the test from our college and 59 from our department (including top 5)
2. Technical Interview
As per my experience if you have minimum basics in your subjects it is easy to get through. you should be able to speak clearly in english with confidence.It is in your hands to get the interviewer into your field.
My Interview was Technical-cum-Management Round
i entered the room around 4 pm. He said me take your seat. I sat on chair before interviewer holding my file on my lap. Through out my interview i was positive, responsive and confident. the interviewer saw my name BHARGAVA RAM KOTI on my resume and said yours is very powerful name isnt' it ..he said. I said "yes sir"
he asked what subject do you Know?
i said only JAVA and nothing more than that. here one thing is important. if you know any subject very well whether if you 1 or 2 it doesnt
matter. It becomes important how you answer the questions. the dont care how many subjects you know. If you know even 1 subject perfect thats enough to crack the interview.
He asked me "Ok Bharagava Ram mention about urself "
I started with my schooling ,intermediate and about my study in BEC .I mentioned my SUN CERTIFICATION IN JAVA. I also said that my college gave me enough exposure to give equal importance for extra-circular, co-circular activities (because i have won many prizes in various technical,literary events) and my academics. Additionally i said that i said my performance was consistent from 10th to B.tech as percentage was very near.
after this,
He then asked me suddenly a managerial question "If you are in a institution, you have done enough hardwork and there is no recognition and other one is recognised.how will solve such Problem"?
I then replied "When i am in a team i want only work to be completed and i said i dont want recognition"
The interviewer said "You should definitely say me the solution"
I responded as "sir, at present i have never such problem .when i get into real corporate world my experience in the industry will solve such kind of Problems"
the interviewer said "ok very good"
He asked About JAVA
I said complete history of Java and how it was comparitvely evolved as of C and C++
He then asked me "give me the differences between c and java"
I replied as "platform independent,garbage collection, pointers"
he then said me to say new differences other than those.
i replied a bit different by explaining turbo c, c++ compilers in c and about javac compiler in JAVA and the information about how java was useful in EJB's of enterprise applications and compared to C language
He suddenly asked the "What is EJB"? so, be cautous about what you speak.!!!
I said about EJB (Enterprise Java Beans) as we have them in 4-1 semester as a part of our curriculum and most recent one!!
He finally asked "When you many oppurtunities like MS and M.tech. Why do you prefer this job????"
I said i am a programmar in JAVA and i won many prizes in technical events.this wants me to established in software industry.My family conditions also compelled me to go to job due to fininancial problems.
he then said "thank you,all the best"
there were some students send to MR (Management Round) and then to Human Resources Round.
3. HR Interview
It was around 2:15 pm on 29th Nov. Before i entered my interview room there was power loss. I reached the and i stopped at the door,but my interviewer called me in the dark with a hand move. I went inside and he asked me to take mn theren y seat.
He then asked me "what man before u came inside why there is a power loss??"
I said as "exceptional case"
he then said "Elders say that when there is light they say something good will happen but what's this????"
I replied him as "when we are dedicated and such kind of obstacles dont have any effect and we have to carry on our own work as there will be problems in life."
"ok" he said
He asked me "Why TCS"?
. i said him few points and he asked me "have the biscuit on table"
I hesitated to take for 3 times as he was repeatedly asking and finally ate with answering the question
he then asked my family background and my sister edcation
I replied him by saying them
Now its the "chocolate turn" he asked asked to eat that but i refused and he said he would give it to next member. I said "noproblem"
He finally asked me two weaknesses
I said my weakness
He said "ok Bhargav ALL THE BEST Thnk you"
MY Interview was over.
I came out and waited for result.
They declared results after 8:30pm and i got placed in TCS. 234 from our college and 35 from our department.
Here one thing is important. You should be very interactive and give positive reponse. My HR interview so strange when compared to others.you should be in a position to handle any situation. When they ask you to say about "Tell me about yourself". Be well prepared to say uninterruptedly.
Finally, ALL THE BEST for your future proceedings

HR interview with Infosys on 07 SEP 2011 in PATIALA
Following is an approximate narration of my HR interview with Infosys. The answers mentioned here need not be correct. But I managed to stay confident and somehow got selected. (I couldn’t remember all of it, but it’s nearly the same)
Note: Most of the questions are raised from your resume, so always have enough knowledge about each thing that you mention. I hope it can help.
“Good afternoon sir” v Good-afternoon, please have a seat.
“Thank you” v Fill up this sheet.
A sheet with columns for my rollno, name and signature was filled.
Give me your resume.
I opened the portfolio, took out the resume and handed over gently
So your father works in NTPC?
“No sir, my mother is a school teacher there and thus we are living in the quarter allotted to us. My father is a businessman”
What kind of business?
“He deals with plastic bottles and their marketing”
Only marketing? No manufacturing?
“Manufacturing as well, but not on that level”
Interviewer analyzes the resume
What is this KPS?
“It is Kalka Public School in New Delhi, I lived there in a hostel during my +1 and +2.”
So what difference did you find in the hostel life?
“I learned a lot of things in the hostel, being independent and understanding people are some of them. Also, as I am the only child of my parents, I learned sharing stuff and adjusting with my room-mates there.”
Other than the unavailability of home-cooked food, what problems did you face in the hostel?
“I missed the guidance of my father, because at home he was always there for me guiding me through every walk of life. This was somaething I had to learn to live without.”
I am talking about the problems in your hostel.
“Oh! In the hostel itself, brooming and washing my clothes was a new thing for me as I never did it at home.”
So how did you manage?
“I learnt it eventually as I had no other option; moreover all my fellow hostellers were facing the same problems so we all helped each other.”
After what time did you wash your clothes? Once a month or once a week?
“Once a week, because I had enough clothes with me to manage for that period of time”
So how did you get into this University, via AIEEE or what?
“Yes, I came here through AIEEE. There was a counselling organized by PTU and as my rank was good enough, I got the seat here.”
So where are you living now?
“I live outside the university in a rented room as I couldn’t get the hostel in the first place due to the shortage of rooms”
How many roomies do you have?
“Earlier I was living alone, but now there are 3 of us.”
Who does the cleaning here? Do you have any turns for that?
“No sir, we don’t do it by turn. All three of us clean the room together once a week by dividing the work. Like… one of us would be brooming while the other would be cleaning the stuff, etc”
And what about the food; who cooks?
“None of us can cook, so we have our food outside. As the university allows us to open an account at the hostel mess, we used to eat there but these days we are relying on the outside restaurants and Dhabas, because we found that the food quality is good here.”
You didn’t find the food quality good in Delhi?
“We have all kind of food in Delhi and with pretty good quality as well. But the hygiene and quantity was not that good as compared to Punjab if we talk about it at the student level. I mean within my budget.”
And what kind of problems did you find here?
“I didn’t find many problems here, as the people are very helping and friendly. I made friends quickly and managed well. Of course the language problem was there at first because I didn’t know Punjabi, but I got over it soon.”
So how many friends do you have here?
“Well I don’t have an exact count of them coz there are many, actually I have been hanging out with a lot of people”
And what about good friends?
“Again there are many and for my birthday if I treat all of them, the count reaches about 40 easily. But if being together all the time is your concern, then there are just 3 of us.”
Which stream do you have here?
“Computer science”
You had it by choice or by default?
“By choice sir!”
Which is the mother branch of computer science?
“I am not sure about that, but it is a kind of science. So maybe the mother branch is Science only”
(Please email me the correct answer at kushal.ashok@gmail.com)
So where did you do your summer training?
“I had my summer training at HCL CDC Ghaziabad and made a project using Dot NET, but I really enjoyed my training at MSME in Delhi, when I learned Mobile Phone repairing. We learned how to check all the components, by using the circuit diagram and a lot of other things.”
Do we have the same circuit diagram for all brands of mobile?
“No sir, each model has a different circuit diagram. Of course the components are mostly the same, but knowing the circuit is very important for repairing.”
Where do you get this circuit diagram from?
“All these are easily available at Gaffar market in Carol Bagh, Delhi. Rather one can buy the whole mobile repairing kit from there as it is the hub for mobile phones.”
So if we bring a mobile from America, can we make it work here in India?
“Yes sir, we can make it work, because the technology used behind is the same these days. The only difference might be coz of the radio frequencies. If the phone supports enough frequency bands, we can make it happen. Also, there are certain codes and methods which can unlock the phone and make it work in a different scenario.”
What are the main causes of defects in a mobile?
“There are three major causes… moisture, dust and shock. For those with shock, we mostly need to check the components but we can try getting rid of the dust and moisture by cleaning the mobile with acetone.”
And you like motorcycling?
“Yes sir, it is my favourite hobby. I have joined a club in Delhi and we organize various trips which are open to all. Generally the motorcycling clubs have some restrictions like… you need to own a particular kind of bike like Royal Enfield. But we never had such restrictions in our club.”
But one still need to have a motorcycle to join, right?
“Yes sir, but one can be a pillion rider as well and we encourage and arrange the rides for those who don’t have a vehicle but want to join”
Do you have 2-stroke or 4 stroke bikes?
“2 stroke motorcycles are not in the market sir, most of them are 4 stroke”
What do you mean by 4 stroke?
“Sorry sir, I do not have the answer for that. But I always try to learn more and more by paying attention and learning from my mechanic when I get my bike serviced.”
(The four strokes refer to intake, compression, combustion (power), and exhaust cycles that occur during two crankshaft rotations per power cycle of the four cycle engines. reference: http://en.wikipedia.org/wiki/Four-stroke_engine )
But as you are so much interested in motorcycling, you must know this right?
“Definitely sir, but I am still learning and as you have mentioned it I am certainly going to Google it when I get back home.”
Which bike do you have?
“I have a Bajaj XCD right now”
What is the horse power that it provides?
“It’s around 12 bhp”
What do you understand by rpm? And how does it affect a bike?
“It is rotations per minute. When one needs to buy a bike, the one which can produce more bhp at lesser rpm is considered to be more powerful. Also there is a bore to stroke ratio which is directly proportional to the engine’s output. The bore means diameter of the cylinder bore and stroke is the length through which the piston moves.”
Ok. Do you have any questions?
“No sir”
Thank you
“Thank you sir, it was really nice talking to you”
Note: Most of the questions are raised from your resume, so always have enough knowledge about each thing that you mention. I hope it can help.
“Good afternoon sir” v Good-afternoon, please have a seat.
“Thank you” v Fill up this sheet.

Tips to Improve Confidence Rapidly
If you want to improve confidence in your daily life, there are many ways you can go about it. This is, after all, a serious issue that affects every aspect of your life. It's worth devoting some time and energy to this goal!
The tips we will be covering here are not meant to be comprehensive, but designed to get you moving in the right direction. Some of them may not seem like they are directly connected to confidence, but they really are. These tips are not listed in any particular order of importance. Focus on the ones that you resonate with.
1. Learn how to breathe! Seriously, people lacking in confidence are usually shallow breathers. If you need help, study yoga, chi gung or look for books or courses on proper breathing. If you don't get enough oxygen, you will tend to feel anxious and lacking in confidence.
2. Get regular exercise. This is another way to get more oxygen, and it also gives you better health overall, which is important for confidence. Pick an exercise program you will enjoy, whether it involves sports, a gym or hiking outdoors.
3. Learn something new. Pick something that you don't urgently need to do, but that you always wanted to know, like a new language, art, dancing, cooking, a musical instrument or sport. Don't pressure yourself to excel at it, just have fun picking up a new skill.
4. Change your habits. Start in small ways, like the routes you walk or drive. Try eating different food, try a new hair style or way of dressing. It doesn't have to be drastic. The point is, people who lack confidence often seek a feeling of safety in comfortable routines -and stepping outside of your comfort zone is something you need to get comfortable with!
5. Get rid of clutter. Dump those old magazines, papers, clothes you'll never wear, broken toys from when you were twelve, etc. This is good advice for almost anyone, no matter what their issues. In this case of confidence, however, this will help you feel more clarity and a sense that you can move in new directions.
6. Pay attention to your speech patterns. Very often, people with low self confidence speak in a low or halting voice. Don't shout at people, but focus on making yourself heard. Do this when ordering your morning coffee, when talking on the phone or at a meeting at work.
7. Don't agree with everyone! Being agreeable is another habit many people need to break. Don't argue just for the sake of it; in fact you don't have to argue at all. The point is not to go out of your way to show people that you agree with them when you either disagree or are neutral. You could say something like, "I can see you point of view, but I haven't quite made up my mind yet." What you say is really not as important as how you feel as you're saying it. It's not your job to boost everyone else's ego!
8. Sit, stand and move with confidence. This may seem either silly or obvious, but how you hold yourself has a lot to do with how you feel about yourself. It works both ways. If you are feeling anxious or lacking in confidence, you will tend to slouch, look downwards and unconsciously try not to take up too much space. Yet doing these things reinforces these very feelings. So if you can sit up straight, look directly at people and walk in a way that shows you are comfortable in your own skin, you will feel this way.
9. Mirrors are your friend. At least, you can make friends with them. Very often, when we are not feeling confident, we don't like to look at our own reflection. This is another exercise that is very simple, and you don' t need to go overboard with it. When you are near a mirror, just look yourself in the eyes for a few seconds. Try to smile and feel some love for yourself. If you are in public, you can do this in a low key manner. Most importantly, don't avoid looking at yourself!
10. Keep up appearances. This may sound superficial, because it is! We are talking about appearances here. Dress in a way that makes you feel good about yourself. Likewise, keep your hair styled in a manner that compliments you. You don't need a gigantic budget to accomplish this. Just make the most of what you have, and pay attention to how you look. This isn't to impress people, it's to show yourself that you are taking the time to look your best.
1. Learn how to breathe! Seriously, people lacking in confidence are usually shallow breathers. If you need help, study yoga, chi gung or look for books or courses on proper breathing. If you don't get enough oxygen, you will tend to feel anxious and lacking in confidence.

4. Change your habits. Start in small ways, like the routes you walk or drive. Try eating different food, try a new hair style or way of dressing. It doesn't have to be drastic. The point is, people who lack confidence often seek a feeling of safety in comfortable routines -and stepping outside of your comfort zone is something you need to get comfortable with!
5. Get rid of clutter. Dump those old magazines, papers, clothes you'll never wear, broken toys from when you were twelve, etc. This is good advice for almost anyone, no matter what their issues. In this case of confidence, however, this will help you feel more clarity and a sense that you can move in new directions.
6. Pay attention to your speech patterns. Very often, people with low self confidence speak in a low or halting voice. Don't shout at people, but focus on making yourself heard. Do this when ordering your morning coffee, when talking on the phone or at a meeting at work.
7. Don't agree with everyone! Being agreeable is another habit many people need to break. Don't argue just for the sake of it; in fact you don't have to argue at all. The point is not to go out of your way to show people that you agree with them when you either disagree or are neutral. You could say something like, "I can see you point of view, but I haven't quite made up my mind yet." What you say is really not as important as how you feel as you're saying it. It's not your job to boost everyone else's ego!
8. Sit, stand and move with confidence. This may seem either silly or obvious, but how you hold yourself has a lot to do with how you feel about yourself. It works both ways. If you are feeling anxious or lacking in confidence, you will tend to slouch, look downwards and unconsciously try not to take up too much space. Yet doing these things reinforces these very feelings. So if you can sit up straight, look directly at people and walk in a way that shows you are comfortable in your own skin, you will feel this way.
9. Mirrors are your friend. At least, you can make friends with them. Very often, when we are not feeling confident, we don't like to look at our own reflection. This is another exercise that is very simple, and you don' t need to go overboard with it. When you are near a mirror, just look yourself in the eyes for a few seconds. Try to smile and feel some love for yourself. If you are in public, you can do this in a low key manner. Most importantly, don't avoid looking at yourself!
10. Keep up appearances. This may sound superficial, because it is! We are talking about appearances here. Dress in a way that makes you feel good about yourself. Likewise, keep your hair styled in a manner that compliments you. You don't need a gigantic budget to accomplish this. Just make the most of what you have, and pay attention to how you look. This isn't to impress people, it's to show yourself that you are taking the time to look your best.

The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coins the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Ans: d

[ Java ] Technical Questions With Answers
Java Technical Questions With Answers
error messages, say to a file?
A. The class System has a variable out that represents the standard output, and the
variable err that represents the standard error device. By default, they both point at the
system console. This how the standard output could be re-directed:
Stream st = new Stream(new FileOutputStream("output.txt")); System.setErr(st);
System.setOut(st);
Q2. What's the difference between an interface and an abstract class?
A. An abstract class may contain code in method bodies, which is not allowed in an
interface. With abstract classes, you have to inherit your class from it and Java does not
allow multiple inheritance. On the other hand, you can implement multiple interfaces in your
class.
Q3. Why would you use a synchronized block vs. synchronized method?
A. Synchronized blocks place locks for shorter periods than synchronized methods.
Q4. Explain the usage of the keyword transient?
A. This keyword indicates that the value of this member variable does not have to be
serialized with the object. When the class will be de-serialized, this variable will be initialized
with a default value of its data type (i.e. zero for integers).
Q5. How can you force garbage collection?
A. You can't force GC, but could request it by calling System.gc(). JVM does not guarantee
that GC will be started immediately.
Q6. How do you know if an explicit object casting is needed?
A. If you assign a superclass object to a variable of a subclass's data type, you need to do
explicit casting. For example:
Object a; Customer b; b = (Customer) a;
When you assign a subclass to a variable having a supeclass type, the casting is performed
automatically.
Q7. What's the difference between the methods sleep() and wait()
A. The code sleep(1000); puts thread aside for exactly one second. The code wait(1000),
causes a wait of up to one second. A thread could stop waiting earlier if it receives the
notify() or notifyAll() call. The method wait() is defined in the class Object and the method
sleep() is defined in the class Thread.
Q8. Can you write a Java class that could be used both as an applet as well as an
application?
A. Yes. Add a main() method to the applet.
Q9. What's the difference between constructors and other methods?
A. Constructors must have the same name as the class and can not return a value. They are
only called once while regular methods could be called many times.
Q10. Can you call one constructor from another if a class has multiple
constructors
A. Yes. Use this() syntax.
Q11. Explain the usage of Java packages.
A. This is a way to organize files when a project consists of multiple modules. It also helps
resolve naming conflicts when different packages have classes with the same names.
Packages access level also allows you to protect data from being used by the nonauthorized
classes.
Q12. If a class is located in a package, what do you need to change in the OS
environment to be able to use it?
A. You need to add a directory or a jar file that contains the package directories to the
CLASSPATH environment variable. Let's say a class Employee belongs to a package
com.xyz.hr; and is located in the file c:\dev\com\xyz\hr\Employee.java. In this case, you'd
need to add c:\dev to the variable CLASSPATH. If this class contains the method main(),
you could test it from a command prompt window as follows:
c:\>java com.xyz.hr.Employee
Q13. What's the difference between J2SDK 1.5 and J2SDK 5.0?
A.There's no difference, Sun Microsystems just re-branded this version.
Q14. What would you use to compare two String variables - the operator == or
the method equals()?
A. I'd use the method equals() to compare the values of the Strings and the == to check if
two variables point at the same instance of a String object.
Q15. Does it matter in what order catch statements for FileNotFoundException
and IOExceptipon are written?
A. Yes, it does. The FileNoFoundException is inherited from the IOException. Exception's
subclasses have to be caught first.
Q16. Can an inner class declared inside of a method access local variables of this
method?
A. It's possible if these variables are final.
Q17. What can go wrong if you replace && with & in the following code:
String a=null; if (a!=null && a.length()>10) {...}
A. A single ampersand here would lead to a NullPointerException.
Q18. What's the main difference between a Vector and an ArrayList
A. Java Vector class is internally synchronized and ArrayList is not.
Q19. When should the method invokeLater()be used?
A. This method is used to ensure that Swing components are updated through the eventdispatching
thread.
Q20. How can a subclass call a method or a constructor defined in a superclass?
A. Use the following syntax: super.myMethod(); To call a constructor of the superclass, just
write super(); in the first line of the subclass's constructor
For senior-level developers:
Q21. What's the difference between a queue and a stack?
A. Stacks works by last-in-first-out rule (LIFO), while queues use the FIFO rule
Q22. You can create an abstract class that contains only abstract methods. On
the other hand, you can create an interface that declares the same methods. So
can you use abstract classes instead of interfaces?
A. Sometimes. But your class may be a descendent of another class and in this case the
interface is your only option.
Q23. What comes to mind when you hear about a young generation in Java?
A. Garbage collection.
Q24. What comes to mind when someone mentions a shallow copy in Java?
A. Object cloning.
Q25. If you're overriding the method equals() of an object, which other method
you might also consider?
A. hashCode()
Q26. You are planning to do an indexed search in a list of objects. Which of the
two Java collections should you use:
ArrayList or LinkedList?
A. ArrayList
Q27. How would you make a copy of an entire Java object with its state?
A. Have this class implement Cloneable interface and call its method clone().
Q28. How can you minimize the need of garbage collection and make the
memory use more effective?
A. Use object pooling and weak object references.
Q29. There are two classes: A and B. The class B need to inform a class A when
some important event has happened. What Java technique would you use to
implement it?
A. If these classes are threads I'd consider notify() or notifyAll(). For regular classes you can
use the Observer interface.
Q30. What access level do you need to specify in the class declaration to ensure
that only classes from the same directory can access it?
A. You do not need to specify any access level, and Java will use a default package access
level.

Advanced UNIX Interview Questions and Answers
1. How do you find which processes are using a particular file?
By using lsof command in UNIX. It wills list down PID of all the process which is using a particular file.
2. How do you find which remote hosts are connecting to your host on a particular port say 10123?
By using netstat command execute netstat -a | grep "port" and it will list the entire host which is connected to this host on port 10123.
3. What is nohup in UNIX?
4. What is ephemeral port in UNIX?
Ephemeral ports are port used by Operating system for client sockets. There is a specific range on which OS can open any port specified by ephemeral port range.
5. If one process is inserting data into your MySQL database? How will you check how many rows inserted into every second?
Purpose of this Unix Command Interview is asking about "watch" command in UNIX which is repeatedly execute command provided with specified delay.
6. There is a file Unix_Test.txt which contains words Unix, how will you replace all Unix to UNIX?
You can answer this Unix Command Interview question by using SED command in UNIX for example you can execute sed s/Unix/UNIX/g fileName.
7. You have a tab separated file which contains Name, Address and Phone Number, list down all Phone Number without there name and Addresses?
To answer this Unix Command Interview question you can either you AWK or CUT command here. CUT use tab as default separator so you can use
cut -f3 filename.
8. Your application home directory is full? How will you find which directory is taking how much space?
By using disk usage (DU) command in Unix for example du –sh . | grep G will list down all the directory which has GIGS in Size.

By using nslookup command in UNIX, you can read more about networking command in UNIX here
Intermediate UNIX Interview Questions Answers
1. What is difference between ps -ef and ps -auxwww?
This is indeed a good Unix Interview Command Question and I have faced this issue while ago where one culprit process was not visible by execute ps –ef command and we are wondering which process is holding the file.
ps -ef will omit process with very long command line while ps -auxwww will list those process as well.
2. How do you find how many cpu are in your system and there details?
By looking into file /etc/cpuinfo for example you can use below command:
cat /proc/cpuinfo
3. What is difference between HardLink and SoftLink in UNIX?
I have discussed this Unix Command Interview questions in my blog post difference between Soft link and Hard link in Unix
4. What is Zombie process in UNIX? How do you find Zombie process in UNIX?
When a program forks and the child finishes before the parent, the kernel still keeps some of its information about the child in case the parent might need it - for example, the parent may need to check the child's exit status. To be able to get this information, the parent calls 'wait()'; In the interval between the child terminating and the parent calling 'wait()', the child is said to be a 'zombie' (If you do 'ps', the child will have a 'Z' in its status field to indicate this.)
Zombie : The process is dead but have not been removed from the process table.
5. What is "chmod" command? What do you understand by this line “r-- -w- --x?

In this UNIX command interview questions interviewer is generally checking whether user knows basic use of "ls" "grep" and regular expression etc
You can write command like:
ls -lrt | grep "^l"
2. Create a read-only file in your home directory?
This is a simple UNIX command interview questions where you need to create a file and change its parameter to read-only by using chmod command you can also change your umask to create read only file.
touch file
chmod 400 file
3. How will you find which operating system your system is running on in UNIX?
By using command "uname -a" in UNIX
4. How will you run a process in background? How will you bring that into foreground and how will you kill that process?
For running a process in background use "&" in command line. For bringing it back in foreground use command "fg jobid" and for getting job id you use command "jobs", for killing that process find PID and use kill -9 PID command. This is indeed a good Unix Command interview questions because many of programmer not familiar with background process in UNIX.
5. How do you know if a remote host is alive or not?
You can check these by using either ping or telnet command in UNIX. This question is most asked in various Unix command Interview because its most basic networking test anybody wants to do it.
6. How do you see command line history in UNIX?
Very useful indeed, use history command along with grep to find any relevant command you have already executed. Purpose of this Unix Command Interview Questions is probably to check how familiar candidate is from available tools in UNIX operation system.

Many options but you can say by using "scp" command. You can also use rsync command to answer this UNIX interview question or even sftp would be ok.
8. How do you find which process is taking how much CPU?
By using "top" command in UNIX, there could be multiple follow-up UNIX command interview questions based upon response of this because “TOP” command has various interactive options to sort result based upon various parameter.
9. How do you check how much space left in current drive ?
By using "df" command in UNIX. For example "df -h ." will list how full your current drive is. This is part of anyone day to day activity so I think this Unix Interview question will be to check anyone who claims to working in UNIX but not really working on it.
10. What is the difference between Swapping and Paging?
Swapping:
Whole process is moved from the swap device to the main memory for execution. Process size must be less than or equal to the available main memory. It is easier to implementation and overhead to the system. Swapping systems does not handle the memory more flexibly as compared to the paging systems.
Paging:
Only the required memory pages are moved to main memory from the swap device for execution. Process size does not matter. Gives the concept of the virtual memory. It provides greater flexibility in mapping the virtual address space into the physical memory of the machine. Allows more number of processes to fit in the main memory simultaneously. Allows the greater process size than the available physical memory. Demand paging systems handle the memory more flexibly.

17. in a race u drove 1st lap with 40kmph and in the second lap at what speed u must drive so that ur average speed must be 80kmph.
Ans: its impossible! if u drove the first lap in 40 kmph, its impossible that the
average speed of both the laps is 80kmph.
for eg. consider one lap distance = 80km.
time req. to cover 1 lap = 80km/40kmph = 2 hrs.
if the avg. speed is 80kmph, then the total time would have taken = 160kms/80kmph = 2 hrs.
same is the case with any other distance u consider. so the avg to be 80kmph is impossible
