Whole-Testpaper

Hi Friends,

This is “Vikram Singh Chauhan” student of Electronics and Telecommunication Engg. from G.H. Raisoni college of Engg., Nagpur.

TCS came to our university for off-campus on dated 28th & 29th of August-2010. A total of 1500 appeared for it and only 36 got selected. The selection process consisted of regular 4 Tcs rounds as

1. Aptitude Test.
2. Technical Interview (TI).
3. Managerial Interview (MR).
4. HR Interview (HR).
 
1. Aptitude test:
 
TCS has changed its aptitude pattern from March of this year as it now uses “TouchStone” software which consists of mostly (about 90%) of the questions on Quantitative section only.
 
There is no need to mugup the model test paper of GRE Barron now. If you have gone through R.S. Aggrawal its sufficient but you need to be really quick while solving the questions as time alloted is not sufficient.
 
Test Pattern:
 
You will be asked to solve 35 questions in 60 minutes and there is negative marking of 33.3% also. But each and every question contains lot of irrelevant data and it consumes hell lot of time to extract useful data from the question. Few questions for your reference are:
 
Q1) There’s a farm having various birds of different weight. Farm has 23 birds weighing less than 15 gm, 35 birds weighing betweem 15 gm to 50 gm, and 12 birds weighing greater than 50 gm. One day accidentally a cunning Fox enetered the farm. After seeing so many birds see decided to pick some birds for its meal for next few days. Fox picked some birds from the farm and went away. How many total birds fox should pick so that it will have minimum 2 birds of each weight group.

(not remembering the options, but I and many of my frends tried all possible probabilties and permutation combination bt our answers didn’t matched any of the given options)

Q2) A roof has two tanks A and B. Tank A gets fileed at the rate of 1.3 litre/hour. Tank B gets filled at the rate (10,20,40,80,..). If after 22 hours the Tank B is (1/16)th filled. Calculate the time required by it to get full

18 more questions which were based on the topics of number system, average, time and distance, time and work, pipes and cisterns, problems on ages. Pay extra attention on probability and permutation and combination.

The result of aptitude test was out in 10 minutes and out of 60-70 students in my batch only 4 got through. I attempted 24 questions. I think if you have solved around 21-22 questions correctly you will get through.

Technical round:
 
After this they called me for the TI. The HR was a man of around 35.
 
I: May I come in sir?
TI: Yeah sure. Take the seat. So vikram what are you doing from past few days?
 
I: Told him abt preparation for TCS and other things.
TI: You are from ETC so why do you want to join software industry?
 
I: Was ready for this question answered to his satisfaction.
TI: It means you are interested in programming so which is your favorite subject?
 
I: I told sir C and Microprocessor.
TI: In which microprocessor you are good?
 
I: 8085.
TI: What are 1byte, 2byte, 3byte instructions?
 
I: Gave him answer which later I came to know was wrong.
TI: What actually happens when a call instruction is executed, Explain in full detail?
 
I: Explained nicely to him.
TI: What are different types of interrupts in up, what are hardware and software interrupts, how are they executed, what, is the difference in hardware and software interrupts and why there is need of them, what is IVT (interrupt vector table)?
 
I: Luckily I was knowing the answers of all the questions so expalined everything to him smoothly and nicely.
After this was the turn of most deadly MR round where you will be given any situation and will be asked to solve it with cross questioning on your every statement. But their was hardly any elimination in this round. Luckily I wasn’t called for this round and was called straight for the final round ie.,
 
HR round:
 
HR: Was a girl of around 24-25.
HR: So how are you Vikram?
 
I: I said fantastic mam.
HR: Have you had your lunch today (as it was aorund 4:30 pm)?

I: No mam didn’t got the time.

HR: So without having your lunch how can you feel fantastic. Don’t you need food for feeling energetic?
I: Was aware of this trap already gave her the answer which impressed her a lot and she complimented me for my answer saying nice answer. (got huge confidence from this).
 
HR: Tell me something about you?
I: Told.
 
HR: Being an electronics engineer what can you do in TCS and how can you help TCS in its development?
I: Told.
 
HR: Tell me about the recent trends in IT industry?
I: Was knowing that this question is being asked to almost everyone so I went prepared with its answer and told him everything which have read in dailies.
 
HR: Then she asked me whether I'm mobile, ready to sign the bond, and wether I am aware of the background check conducted by TCS.
I: I aggreed on all her questions and this brought an end to my interview.
 
After around half an hour results were announced as I was last to go for the HR I had to wait very little for the results and indeed it was very pleasing to listen ma name in the voice of HR which confirmed me as a TCSian.

Best of Luck!

Vikram Singh Chauhan.
