TCS Fresher Job Interview Paper Pattern :
19-Nov-2010

**Company Name **: TCS**Type :** Fresher**Job Interview,** Question Paper

I am from CSE, SRKR engineering college, bhimavaram.We had campus placement
drive by TCS on 19th November 2010.**Total No. of Rounds:**

- Written Test
- Technical Interview
- MR
- HR

**Round 1:** **Written Test:** No Reasoning, No Verbal,
Only Simple Aptitude Questions With Negative Marking (1 Mark For 3 Wrong
Answers) 35 Ques-80 Minute. I heard it to be 1hr but we were facilitated with a
bonus of another 20 min that day. TCS is now using a database for written tests
called TOUCH STONE. It consists of around 2.5 to 3 lakh questions probably of a
finite set of models. Thus the data may change but the models will be same. SO,
my sincere advice is: refer the TCS old papers from this site during your
preparation. And also from tcs cse strikers. com It will help you a lot.I could
not remember the questions exactly but I assure you the model is the same.**Note: **All the questions in the actual test will be preceded by lot of
unnecessary data to confuse you.I am posting only the main part of each problem**Q.1** There are two water tanks A and B, A is much smaller than B. While
water fills at the rate of 1 liter every hour in A, it gets filled up like, 10,
20, 40, 80, 160 in tank B. (At the end of first hour, B has 10 liters, second
hour it has 20 liters and so on). If tank B is 1/32 filled of the 21 hours, what
is total duration of hours required to fill it completely?

a) 26

b)25

c)5

d)27

Solution: for every hour water in tank in B is doubled, Let the duration to fill
the tank B is x hours. X/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so, 2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8) th part in 23 hours,(x/4)th part is filled in 24 hours, (x/2) th
part is filled in 25 hours, (x) th part is filled in 26 hours So answer is 26
hours.**Q.2:** 6 persons standing in queue with different age group, after two
years their average age will be 43 and seventh person joined with them. Hence
the current average age has become 45. Find the age of seventh person?

a) 43 b) 69 c) 52 d) 31

solution Total age of 6 persons is x hours,after two years total age of 6
persons is x+12 Average age of 6 persons is after two years is 43 So
(x+12)/6=43,then solve x, After 7th person is added then (x+7th person age)/7=45
So we will get 7th person age easily**Q.3: **A man travels from A to B at 4 mph over a certain journey and
returns over the same route to A, at 5 mph. What is his average speed for the
journey? Solution: Average speed=(2*x*y)/(x+y)**Q.4:** A toy train produces 10 different sounds when it moves around a
circular toy track of radius 5 m at 10 m per min. However, the toy train is
defective and it now produces only 2 different tunes at random. What are the
odds that the train produces for consecutive music tones of the same type?

a) 1 in 16 B) 1 in 4 c) 1 in 8 d) 1 in 32**Solution:** Initially it produces 10 sounds and the defect came and now it
produces only 2 different sounds and consecutively so there are totally 2 sounds
and we have to select on sound and the probability is Â½ and it produces the
same sound consecutively for 2 times so the probability becomes Â½*1/2 ie Â¼**Q.5**: A scientist was researching on animal behavior in his lab. He was
very interested in analyzing the behavior of bear. For some reason he travelled
1mile in north direction & reached at North Pole. There he saw a bear. He then
followed the bear around 1 hr with a speed of 2km/hr in east direction. After
that he travelled in south direction & reached at his lab in2 hrs. Then what is
the color of the bear?

a) White

b) Black

c) Gray

153 m long and it is to be cut into pieces of 1m length, then how many cuts are
to be made to cut the ropes into 153 pieces?

a)153

b)152

c)154

d)155**Solution:** To make it 153 pieces we have to cut 152 times so obviously
after last cut we got 153rd piece**Q.7**: 10 men and 10 women are there, they dance with each other, is there
possibility that 2 men are dancing with same women and vice versa?

a) 22

b) 20

c) 10

d) never

solution: NEVER**Q.8**: 20 people are there, they are shaking hands together, how many hand
shakes possible, if they are in no pair of cyclic sequence.

a) 19

b) 21

c) 28

d) 7**solution:** answer is 19

For this type of problem answer will be n-1. but this formula will vary if
cyclic sequence is allowed..**Q.9**: there are some cycles and 4 wheeler cars. on tue there are 190
wheels. then how many cycles are there on that spot?**solution: **check from options. multiply each and every option with 2 and
subtract result from 190.if the obtained result is exactly divisible by 4, that
will be the correct answer**Q.10:** A father had three children. He had 7 pennies. how can he eqally
distribute the fruits among his children if A watermelon costs 1 penny, 2
oranges cost 1 penny and 3 grapes cost 1 penny a)2 melons, 1 orange, 1 grape b)
2 melons, 2 orange, 1 grape c) 1 melons, 2 orange, 1 grape.**solution: **if he buys grapes with 1 penny, he can distribute 1grape each
equally as there are 3 grapes. then he has 6pennies left with him so with
3pennies he will by 6oranges and distribute 2each. with other 3 rupees he can
buy 3watermelons and distribute one each therefore,**answer is:**1water melon, 2 oranges and 3 grapes

**Q.11: **The age of the two friends were in the ration of
6:5. If the sum of their ages is 55. Then after how many years their ratio will
become 8:7?

a) 11

b) 7

c) 10

d) 12**Solution:** 6x+5x=55, so x=5, put first ratio after substitution is
(6*5)/(5*5) and second ratio is 40/35 So difference in numerators 40-30=10 years**Q.12: **A horse chases a pony 2 hours after the pony runs.Horse takes 3
hours to reach the pony.If the average speed of the horse is 81Kmph.Then what is
the average speed of the pony?

a) 46.4

b) 51

c) 53.4

Guys since there is negative marking try not to make guesses. Cut off for
selection may vary between 15-21 depending on your college and the situation.
(It may also vary among different branches) I am not sure about the cutoff at
our college but I answered 21 questions correctly and cleared the written test.
One of my friends who answered only 15 questions was also selected. Getting
prepared for the written test by referring all old papers of the new test
pattern is more than enough to crack this test..**Round 2: Technical Interview:**

In order to get through technical interview, it,s better to revise basics of all
subjects. Only basic concepts will be asked. IT's HARD TO GET THROUGH THIS
UNLESS WE ARE CONFIDENT ABOUT WHAT WE SPEAK. They check our attitude Even if you
do not know the answer, do not get nervous. It,s a minor issue. There was one
interviewer per panel. The interviewer was very friendly. I did not feel tensed.
I spoke very confidently as if I was speaking to a very familiar person With a
cute smile on my face throughout the interview**Questions posed to me are:**

1. Tell me about yourself?

2. Which languages are you familiar with?

3. Rate yourself for each subject.

4.What is a semaphore?

5. What is diff between CPP and Java?

6. What is static void in Java,s main statement?

7. Who will initialize the objects in Java?

(I said wrong answer:-"compiler" but interviewer corrected it & said that the
correct answer is Java Virtual Machine)

8. Some other question (I could not remember the questions)

I do not know the answer for that and said the same to him..

9. Why TCS?

10. Given an opportunity how will you see yourself in the next 5 years?

That,s it. I was very confident about my performance and came out with a smiling
face. As it was already 7.30 pm within a few minutes I was directed to M.R
interview panel**Round 3: M.R**

I entered the room with the same confidence. again there was only one
interviewer in the panel

Me: Good Evening Sir

Interviewer: Good Evening! How was ur day today?

Me: some what uncomfortable due to the heavy rain sir..:)

I: You might be familiar with the questions being asked here. by discussing
experiences from your frnds outside. u people are faster than the WWW.

Me: Yes sir (smiling)

I: so what are the questions that you gathered?

Me: why TCS? why CSE? only these two sir..every one are saying these two only!!

I: so I am not going to ask them again bcoz u might b ready with well prepared
answer

Me: yes sir fine. I am ready to face any questions

I: k. good what is ur weakness?

based on my weakness sleeping I was given a situation and was asked how I
will come out of that. nswered that and I was asked to leave.**Round4: H.R**: I was asked only a few questions:

1.Are you familiar with the TCS 2yr bond?

2.Willing to work any where in india?

3.How can u manage ur team if there are any controversies?

(this was asked bcause i mentioned in resume that i can do team work
efficiently)

4.Do you have any questions to ask?

One mistake i did in all the three interview rounds is i sat in the chair even
before i was asked to sitResults were announced the next day My Name was
announced first among others in our department I felt very happy to be a part of
TCS. 268 from our college were selected. We shouted to the roofs that evening.
GUYS refer old papers; prepare the basic topics from each and every subject.

Important Among All Speak Confidently. The More Confident You Are The More Will
Be The Chance Of Getting Selected. Meet U In TCS.

All The Best**Exam/Interview Date :** 19-Nov-2010**No of Rounds : **Aptitude Test, Technical Round-1, Client/Manager Interview
