BARC Interview Questions for Computer Science Candidates

It was around 4 a.m. when i woke up in the train by alarm. Mumbai was about to come. It was the first time i was going to any metro city. What a soothing weather. I reached there 2 days before the interview. One of the main reason was the written exam of ECIL was going to be held just one day before the interview of BARC. My neighbor who is working in Indian Navy right now and placed in Mumbai booked a room for me in a hotel especially dedicated to armed force employee and their families. I was a  bit tired after a horrible journey of 40 hours. So I preferred to take rest for the whole day. In the evening he helped me to explore Mumbai. I visited Gateway of India, Taj Hotel, Nariman House, Marine Drive, Lover's Point and finally had a glimpse of Vankhede Stadium. Most of the people suggested me to leave the exam of ECIL and prepare for the interview of BARC but i wanted to be in safe position. So i went on to appear for the written exam of ECIL and you know it was the first time i experienced the journey in Mumbai Locals. Next day was going to be very crucial in my life. I relaxed myself saying the famous dialogue of Amir Khan "All will be well. Don't worry." and then tried to sleep but sleep was far away from me and i really didn't know when i slept that day.

Finally the deciding day comes. When i woke up i smell wines/darus/madiras around my room. I became very angry but i couldn't do anything. Anyhow i took a bathe and started dressing up. Suddenly my neighbor's call came and he told that his duty is extended to 10 a.m. and he will not be there to go for interview with me.
Now i have to make arrangement for myself. Mumbai is very big and crowded city and it is very difficult for a stranger to go anywhere. I skip my breakfast, went in hurry to the nearby local train stop. I forgot to worship also which i usually do daily. Local trains of Mumbai is very crowded in morning time especially because everyone is going to his workplace/office. Anyhow i reached the BARC School just in time. Still i haven't taken the breakfast. I raced away to the auditorium and what i saw is so many grooming and happy faces making themselves ready for the interview. I became happy because i was also among them.

Now its time for registration process. When my turn came i found that i had not my 7th semester result with me. How could i be so careless. I became slightly nervous and that is the reason why when i had to submit the BARC copy of challan by dividing the challan receipt vertically into two halves, i divided that horizontally. Uff.. What was happening. Anyhow the registration process completed and i was allowed to appear for interview with the condition that in case i am selected i had to submit the scanned copy of my 7th semester result within 1 week.
My turn was 3rd for interview and there were two rooms. So it became 2nd for 1st interview room. I knew that the interview of the 1st guy was going to be long and i had ample time for taking my breakfast. The interview was being held at the 12th floor of the building and i don't knew at that moment where the canteen is? Don't know why but i decided to quit my breakfast and take a 1+1/2 lunch after my interview. Finally my turn came. It was around 11:38 am. I entered the room and what i saw is there was an elliptical table, 7 experienced people had sat around that. Oh my god.!!

Questions asked -

How are you Mr. Raj?
Where are you staying in Mumbai right now?
From which college you completed your B. Tech?
Have you any job right now?
(Probably i shouldn't have told about my TCS job.)
Tell me your favorite subjects.
C , Data Structure , OS , DBMS , Networks.

C -

    Which compiler did you use for c programming and which version?
    Which shortcut is used for compiling and running the program on this?
    Can you explain the process of compilation?? (asked many things concerned with compilation process while I was explaining like preprocessing, linker , libraries , assembler. In other words you can say the real fight starts.)
    Write any program in c language and explain everything written in that. (I wrote iterative version of factorial program. Everything was correct. Thank god. I used %d for printing the factorial value. So he asked what will happen if i input the number 100 in program. I explained successfully (for >65635 concept in %d)).
    Next question. You can guess from the previous question--- Yes. It was about recursion. They asked - Do you know the term recursion? Why don’t you use that concept for this program?
    Write the syntax for the declaration of array and structure. What is actually passed when we pass array and structure in a function? (asked many things about passing of array and pointers too.)
    (too many explanations... i started feeling tired.)

DATA STRUCTURE –

    What is data structure?
    Name the data structure you knew so far and tell the use of everyone. (I tell the use of each. They asked the next questions about the use of stack which I told them.)
    How can you use the stack to reverse the string? Can you write the program for that?
    What is preorder, postorder and inorder traversal?? I explained them. Then they asked me to write the code for these traversals. Till I wrote the recursive version of preorder traversal, they asked me if I can write an iterative version of that program. I wrote that.
    You said array and linked list are the linear data structure. What is difference between them?? Next questions – about declaration of linked list.
    What is the demerit of linked list? I explained the demerits and explained too how circular linked list and doubly linked list removes that.
    Can you write the program for reversing the linked list?

I was a bit tired now. I asked for some water. wo bhi to mere samne samosha kha rahe the.

     What is balanced binary search tree?
    Can you write the program for determining whether a given binary tree is balanced or not?? (I told the way how to do that only.)
    What is hashing? How to avoid collisions?
    Which sorting technique is best and why?

Operating System –

    Explain what happens when we press power button of our computer i.e. which process executes. (I start with POST test.. they impressed.. even the lady who asked that question said that I asked this question to many but everyone started with booting… next questions about booting , volatile memory , RAM & ROM , secondary memory , hard disks etc.).
    Which OS is installed on your computer? What is difference between vista ,xp and 7
    What is semaphore?
    What are the conditions of deadlock?
    Can you explain Banker’s Algorithm?
    Which programs did you do in your b. tech. course in OS? Which data structure did you use in them?
    What is paging?
    What is thrashing? How to get rid of it?(Working-set model concept)

DATABASE MANAGEMENT SYSTEM –Before the expert asked any question, i asked again if I have some more water.Honestly I was exhausted till then.

    What are the advantages of DBMS?
    How consistency and non-redundancy is ensured by DBMS?(Normalization)
    What is the role of DBA?
    Do you know SQL? On which software you practiced SQL in your college life and what did you do in your DBMS lab? (kya batata  kuch kiya to tha nahi bol diya student ke info store karne ka table banaya tha)
    Queries for insertion, updating, adding attribute and changing attribute.
    2 Phase locking. How it ensures concurrency control?
    What are disadvantages of 2PL?
    Conflict serializability?

Networks –

    Name the layers of OSI layer and explain the function of each layer.
    What are repeaters, switches, bridges, routers, gateways?
    What is CSMA/CD?
    What is the distance vector routing?

Here, my interview ended. I was told to go now. Suddenly the words of Senior stroked my mind “if you are selected, they will give a white paper after the interview”. I was not able to face any interviewer face at that moment but anyhow I saw the chief interviewer’s face. He was smiling at me. I thought “kamina ye hans kyun raha hai”. But they didn’t give me that white paper. Bhari kadmon se mai room ke bahar aya hi tha ki peon ne andar se ake mujhe rukne ko bola. I thought “ho gaya kya be.. hey bajrang bali… plz..” but the peon again came outside the room after few minutes and said to me “you may leave now… :( :( ”.

And thus the dream of being a scientific officer in BARC remained a dream for me.. :( :(

BARC Interview Questions for Mechanical Engineering

My interview Experience with BARC (Mechanical engineering)

GATE Papers - Click Here
 
BARC Question Papers: Click Here


I qualified the written exam conducted by BARC and attended the interview.
First let me tell you that this is the most genuine and toughest interview among all the PSUs. This is the best interview methodology that they adopt.

They just ask for very basic questions of Intermediate (12th) level and want to check the basic understanding. Almost all the questions are practical questions no direct relation with the knowledge of core technical. In this way they look for the way you approach to solve a problem.
Because the post they offer you is scientific officers, post. This is a research oriented job that requires the great skills and knowledge to solve a real practical problem. So, this was a basic idea about the interview. Now let,s talk about the methodology, actually they ask you 4-5 subjects in which
you are more comfortable and ask the basic questions. But keep in mind that you are really comfortable with those subjects and you should be thoroughly prepared. Because they will try to divert you from your answer and will drill on topic till you surrender. But anyway you don,t worry
even if you are not able to solve a problem for whole but the way you approach and the basic concepts should be correct. They are generally the minimum time.



Interview is more than 45 minutes. Even the person they know will not be qualified; they drill him at least for 45 minutes. As the interview timing cross more than 45-60 minutes, your chance goes on increasing to get selected. Finally If they are satisfied with your performance then they give you a medical slip that insures your eligibility fir the interview. Final Result depends on the no. of posts and the merit list prepared on the basis of marks you achieved in written and interview. I wish you all the best for your interview.

It is well known that hard work and the luck both are that major factor that plays important roles in every exam. Your Luck also plays an important role that by which panel you are going to be interviewed. During my interview I was a victim of bad luck so I could not qualified the interview.
I had heard that the panel members being very helpful they bring you out of the pressure if you feel during the interview but this was not true in my case.

Anyways, I entered in the room, there were 5 members. The committee chairman asked me about my hometown. The whole conversation was in Hindi, so the people who are from Hindi background they don,t need to be afraid of this problem in PSU interviews.

Then he asked me "Is it your first interview or you
have gone through any other interview?", Me: "Sir this is my first interview". This normal conversation is just to make you feel good and to make
you comfortable.

Chairman: So you have done your B.Tech from IIIT?
Me: Yes Sir.
Suddenly another person interrupted as he was looking at my cv, he told to the chairman that I got first Prize in solid modeling Contest. This was a curse for me for that interview.
Chairman: So you got first prize in Modeling?
Me: Yes sir.
Chairman: What is Computer Aided Design?
Me: I told.
Chairman: You have been taught the Finite Element Methods course?
Me: Yes sir.
Chairman: Can you do the analysis of a cylindrical pressure vessel?
Me: No sir, actually we just learnt the analysis of one dimensional objects.
Chairman: But you know the basics of analysis steps?
Me: Yes sir.
Chairman: What will be the first step?
Me: We will take the symmetry and will not require going through the analysis of whole section.
Chairman: Draw the element of symmetry?
Me: I drawn.
Chairman: Next step?
Me: Boundary conditions and Forces.
Chairman: What will be the boundary conditions, forces etc.....?

I could not give the answers, and the trials were wrong and I was totally confused. but he rammed me a lot and wasted almost 10 minutes.

It was a bad impression that lead me through the darkness.
Then he asked me to put the name of subjects I studied in B.Tech as our curriculum is different from other colleges curriculum, It has major emphasize on Design. So under pressure I was not able to recall the subjects. I started to recall them and listed on the paper but didn,t minded to put them in the order

I prepared. Actually I prepared Material science, Thermodynamics, Heat Transfer and Micro Metal Forming (for the fabrication of MEMS devices, a recent topic). So they just started asking the questions randomly from the subjects they got in that list. After a sometime chairman asked me about the subjects I am comfortable. I told and given the preference to Micro-Metal Forming that was a new topic for him and he decided to get out of the topic and asked about the issues when we go through the micro forming. I told that as we go from macro size to micro, the strength, isotropic behavior and surface roughness changes and affect a lot. Then he asked how surface roughness comes into picture?

Me: As material thickness approaches towards micro size, the no. of grain boundaries becomes fewer and grain boundaries sizes are in the order of microns so the very early surface has a lot of deviations that comes in picture. Then he asked: What is inside the space between two grain boundaries; Gas or Vacuum?
Me: Sir Vacuum. He Said: You are wrong, go and refer the books. and in this way he came out of the topic that he was trying for.
So, I will suggest you not to give any new topic as the persons taking interview may or may not be comfortable with that and it may be a curse to you.
In Thermo... he asked
He: there is a cylinder-piston system that contains a gas, a weight W is kept on piston what will be the pressure?
Me: Sir W/(g*A)---A: area, g: gravity (It was wrong actually I was in such a pressure that to calculate the pressure I was using the formula M/A)
Then another person asked me about "g", why I am using it ? I confidently said: sir to get the mass from weight
He knew that I am confused so he asked me to derive it,s dimension I derived then he asked me to derive the dimension of force by area and he asked me to compare, and I found my mistake. I said sorry and then
He: I am giving it "Q" all the boundaries are insulated so that no heat goes outside, calculate it,s final volume?
Me: I was confused and was asking about a lot of irrelevant information needed to solve.
He: This is all I told you now calculate the volume...no other information.
I could not derive it.
Then......Fluid:
He: I am having an wedge shaped vessel (triangular shaped) I want to know the water level at different places, what will be the levels of water at different tubes?
Me: Same level in every tube.
He: why?
Me: because of fluids property...pressure at a level is same at every point So the height raised will compensate for it.
He: ok so, pressure is constant at all the points in same level but different at different levels?
Me: Yes sir.
He: So if I make two holes at different levels and fit a tube at outside from the vessel then water will flow?
Me: yes sir.
He: If I place a turbine in between the pipe then will the electricity produced?
Me: No.
He: why?
Me: because water will flow once only.
He: but pressure difference is continuously acting at two different levels?
Me: as once water flows and the section gets filled pressure at the same level in vessel and pipe will be same, So no way it will flow again.
This was a section where I was somewhat comfortable and answered correctly.
SOM:
Shear stresses, how shear stress comes ....Is bending stress and shear stress same and a lot....they make me totally confused.
Mohr,s Circle related questions. That I replied correctly.
As you know that I am from Department of Mechanical Engineering. I qualified the written exam conducted by BARC and attended the interview.

BARC General Interview Tips

General tips:
In BARC interview, conceptual aptitude is examined rather than just the mere knowledge of the subject....that means u need to know the subject in great detail with complete understanding....just cramming a formula or cramming a definition will not work...u need to understand the basics behind any formula or definition....

Generally, interview panel has 6-8 members headed by a Chairman of the Committee. Each member asks questions....u r asked about ur favourite topics(generally three) and questions are focussed on that topics...they examine whether you have understood the subject or have just read it...they may start with a question and can go into the minute detail of that....it may happen that you may not answer a question completely but u know the basic fundamental. The knowledge of basic fundas pleases the committee very much.

One thing I wud like to mention here that the people here are very cordial and co-operative and they want every candidate to clear the interview...they provide ample hints and help you wherever you get stuck..the interview becomes more like a discussion session and a candidate feels great after coming out of the interview.

If your interview lasts for abt an hour or more then u have bright chances for a success.For Science people interview may become a bit lengthy and committee may also ask questions from other fields apart from the field u mentioned as your choice.

So, the crux is, identify your strong areas, study in great depth, develop thorough understanding and be positive and confident. A lot of time is left, u can sharpen ur skills during this time.


The time which u spent in the interview room will give u an indication of ur success...if ur interview is getting stretched and u r giving satisfactory replies then u may sense ur success...generally 1.5 hrs to 2 hrs is the time which a successful candidate spends in the interview room...u will know the result the moment ur interview gets over...if u r selected for BARC Training School you will be given a slip indicating a referral for Medical examination...if u get that slip u may congratulate urself for qualifying what is considered as the most trying technical interview in the country...
however if ur interview lasts for more than an hour and u r not being referred for medical test, u may still remain positive as you may be selected for other Training Schools of DAE like NPC Training School, NFC Training School etc....final results are however declared in the third week of july say around 18-25th July...

Joining date is always 1 September of every year.




For computer science candidates:
(Excerpt's from candidate experience)
Hii guys i cleared the interview on 17th june 2008 my interview lasted 1.5 hrs
Do all u r bascis of OS C C++ Data structures and AOA very well
Do pointers in C and all C++ basics very well
They try to confuse u a lot but be firm on u r answers
also they give enough hints to answer !!
Do all basic fundas thats the trick !

(Excerpt from Naveen's experience, successful candidate)
Im from computer science.....my interview was completed 24th june..The interview is memorable experience to me...just they are asking questions from our favorite subjects..I said only three subjects...they immediately said tell 2 more subj.... interview panes is very cool no need to tense......i said my fav subjects Data structures and C,C++,Computation,Algorithms, operating system....
they started from Data structures and c
questions from DS:
1.give 4 applications of each data structure??
from stack to graphs
2.write code for insert a element in middle in the linked list?
3.wat is the diff b/w arry and linked list?
4.wat diff b/w macro and function?
5.which searching tech more useful 4 linked list?
6.write code 4 binary search tree?
7.when the stack is full n empty similal type questions from queue,circular queue...
8.tell diff b/w macro and function?
9.way is inline funtion?(from c++)
from algorithms
if i wrote any program code immediately they said measure time complexity of ur program??
and many more from basics in c and ds
From OS:
How O/s manages data??
draw process state diagram?
wat is system call?
memory is very cheap in these days why these many memory techniques needed??
they are asking more questions from memory management..they are not asking much inner concepts.. some times they are asking silly questions..at that time testing our patience.....be patient at that time....my interview duration 1hour 15min...
even though im not selected i tought my experiece will useful to someone......
For accommodation lot of problem in my day be ready with alternative sources


For electronics candidates
(Excerpt's from candidate experience)
The interview starts with a normal talk like where u from etc etc, then they ask the subject u studied.... i said three n stopped... then they asked tell us some more subjects.. so after i told a list of subjects they settled for 5 subjects. (digital, semiconductor, micro controller, VLSI, Linear Integrated circuits) first they will ask u about ur BE project so be very clear in it don't get stuck up in project anywhere... bring your project report along with you. the questions will not be like the one which we r asked in our college vivas... they will be specific n application oriented. they will not ask u the properties the make up n all... all they want is u to use the info u have to design n get the solution of the problem they will give you. (for me they didn't ask any characteristics n all that does not mean they will not ask at all. come prepared) they used to give me inputs n outputs which was desired by them n asked me design using op amps or design using logic gates....... the overall interview is fun filled interaction with the panel there r jokes cracked be relaxed n laugh out along with the panel if u get stuck somewhere while designing or telling the answer u will be pushed a lot... they throw u ample of hints such that u can pick up from where u got stuck. they will pull u to the solution

(Excerpts from another successful ECE candidate)
i was interviewed for 1.40 hr it was really a good experience all (6)committee members were very very helpful(every interview they starts with mentality 2 select u but rest is in ur hand ) .they asked some formal questions to make u feel comfortable after that they asked my favorite subjects i said ..Electronics devices(including opamps) ,digital ckt & systems ,network theory& analysis n stopped then 1 member said name some more ...then i added analog ckt and tv&radars(thanx to recently ended 8th sem) ..friends i think its better to name at least 4 subjects in decreasing order of ur interest or preparation coz panel will follow d same sequence of subjects 4 questioning so ur 1st fav. subj. will help u to get 1st impression (whole performance will b considered but at least by this u cn gain confidence)........one more thing while explaining any thing on paper try to cover each n every minute detail(including graphs& characteristic curves) & never give any ans. in hurry no matters how well u know abt that for eg :while explaining ohms law never 4get 2 add "keeping all physical condition constant"(of course they r nt askin ohms law

For electrical candidates:
(Excerpt's from candidate experience)
interview started with formal questions like
have u placed in any company if yes then why did u come for barc.
what is ur final year project.(so that u can feel relaxed). of 6 memebers in commitee one have of them started about favourite subjects.i said conrlsys,power sys,machines.
they asked me to about which subject to start first .(control sys).but started with very simple networks . i have answered there question one of the mamdam gone through marks memo and found that i have pulse and digital ckts so she asked about output of skt with rc ckt and diodes (not tough but requires careful observation)and wave form for o/p with pulse i/p.and what happens when resister value is changed with wave forms and transient analyssis of charged inductor (it too requires careful observation).they also concentrated on filters design through control system root locus and significance of poles with respective to filters. then one fo then sir asked me to choose topic in machines. i said induction motor(3 phase).( now tough times started )
asked principle of im (very easy). and asked to draw characteristics drawn now on that graph all question based like stable operational point in graph variation of i/p parameters
and there effects on the system( i felt very tough at beginning but they directed (hinted) with small questions which very easy and very useful to answer final conclusion( big ques)).i.e they are trying to help u to answer complicated ques with simple basic principle u know.(this is the best part of interview because i thought i can never there ques but at end they made me to answer it through simple fundamental i know. i felt like scientist there it self :)) they always help u if u r strong at fundas and able to correlate hints given by them to form final anser.
then they started asking me about ( said not explain but asked to give me short answers) skin effect,ferrentier effect,fault current,hvdc uses

For Instrumentation and Control Candidates:
(Excerpt's from candidate experience)
The panel consisted of 8 … the chairman was very friendly… they made me comfortable… and then asked my favourite subjects for the interview..
I had prepared Industrial instru, process control, sensor & transducer , transmitter and telemetry…
They asked me which subject to start with and I said any one…
They start with RTD.. first asked me to write the chr. Equation, then to find out sensitivity from it.. then drift,span, gain from it.. then to do linear approximation of it….
In between they were also asking about some definitions of accuracy, sensitivity etc..
Difference between gain and transfer function..
Actually where the bookish knowledge ends … there question starts … then they went to wheat stone bridge and grilled me about null deflection etc… why it is not used these days.
