**TCS Fresher Job Interview Paper
Pattern: 03-Jul-2011**

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

On 15/01/2011 TCS conducted written examination. Around 410 students participated and finally 256 students were selected in this written examination and then after INTERVIEW session finally 173 students were selected. And by this figure our college has made a record of maximum no of selections in M.P.

**So Selection Procedure is divided into 3 stages:**

- Written Test
- Technical Interview
- HR interview

**1. Written Test:**
Written test consists of 35 questions 80 mins, It is a online test.**Preparation: **

**Q1.** (1/2) of a number is 3 more than the (1/6) of the same number?
**a)** 6 **b)**7 **c)**8 **d)**9 **Solution:** Let the number be x, ((1/2)*x)=3+(1/6)*x, Then solve x

**Q2.** 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

**5**

c)

c)

**27**

d)

d)

**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.

**Q3.** Out of 7 children the youngest is boy then find the probability that all the
remaining children are boys **a)**1/64 **b)**1/32 **c)**1/128 **d)**1/256 **Solution:** Probability of a boy or girl is ½ So for remaining 6 it’s – {1/2}^6=
1/64

**Q4. **A lady has fine gloves and hats in her closet- 14 blue, 20 red, and 18
yellow. The lights are out and it is totally dark. In spite of the darkness, she
can make out the difference between a hat and a glove. She takes out an item out
of the closet only if she is sure that if it is a glove. How many gloves must
she take out to make sure she has a pair of each color?**a) **50 **b) **8 **c) **40 **d)** 42**Solution: **This is the most repeated question in Tcs so prepare it well It has no
logic but it’s answer comes like this :- Firstly add 2 max values i.e 20+18=38
Then add 2 to answer i.e. 38+2=40 so this is the answer.

**Q5.** Sangakara and Ponting selects batting by using a dice, but dice is biased.
So to resolve, Ponting takes out a coin. What is the probability that coin shows
correct option? **a)** 1/2 **b)** 1/6 **c)** 1/12 **d) **6/10 **Solution:** is ½.

**Q6.** On planet korba, a solar blast has melted the ice caps on its equator. 9
years after the ice melts, tiny planetoids called echina start growing on the
rocks. Echina grows in the form of circle, and the relationship between the
diameter of this circle and the age of echina is given by the formula d = 4*√
(t-9) for t ≥ 9 where d represents the diameter in mm and t the number of years
since the solar blast.Jagan recorded the radius of some echina at a particular
spot as 7mm. How many years back did the solar blast occur? **a)** 17 **b)** 21.25 **c)** 12.25 **d)** 14.05**Solution:** radius =7mm, then diameter 2*radius, substitude diameter the in above
equation you will get answer

**Q7**. Ferrari S.P.A is an Italian sports car manufacturer based in Maranello,
Italy. Founded by Enzo Ferrari in 1928 as Scuderia Ferrari, the company
sponsored drivers and manufactured race cars before moving into production of

could go 4 times as fast as Mohan's old Mercedes. If the speed of Mohan's
Mercedes is 35 km/hr and the distance traveled by the Ferrari is 490 km, find
the total time taken for Rohit to drive that distance.**a)** 20.72 **b)** 3.5 **c)** 238.25 **d)** 6.18 **Solution: **Speed of Ferrari =4*35=140,time=distance/velocity,

**Q.8.** Entry ticket to an exhibition ranges from 1p to 31p. You need to provide
exact change at the counter. You have 31p coin. In how many parts will u divide
31p so that u will provide the exact change required and carry as less coins as

test, how many mice's are required to find the poisoned can? **a) **3 **b) **2 **c) **6 **d) **1 **Solution:**-1 Because in that problem they didn't mention the details like,one
mice take 2 hr or 3hr etc..they told only 24 hr to test..so 1 mice is
enough..rest are useless words.

**Q.11. **A Sheet of paper has statements number from 1 to 20.Statement n says "At
least n of the statements on this sheet are true".which statements are true and
which are false. **a.** The even no statements are true and the odd no statements are false. **b. **The 1st 13 statements are false and rest are true.**c. **The 1st 6 statements are true and rest are false**d. **The odd no statements are true and even no. are false.**Solution:**- this type of question was repeated 3 times but for different case.
For this type of Questions, follow this: At least- Ist half are true, Last half

**Q.12.** On the planet Oz, there are 8 days in a week- Sunday to Saturday and
another day called Oz day. There are 36 hours in a day and each hour has 90 min
while each minute has 60 sec. As on earth, the hour hand covers the dial twice
every day. Find the approximate angle between the hands of a clock on Oz when
the time is 12:40 am. **Solution:**- 89 deg 36hrs a day mane the clk will b of 18hrs.

18hrs covrs 360deg thus 1hr covrs 20deg
12 hrs covrs 12*20=240deg ekhon,1 hr in 90min thus in 90min the hour hand goes
20deg tai, for 1min hr hand goes 2/9deg sei jonne, for 40 min hour hnd goes
(2/9)*40deg=80/9deg=9deg(approx) thus hr hand covrs total of 240+9=249deg now
min hand covrs=40*4=160deg (karon, 90min=360deg 1min=4deg) thus angle betwn them
249-160=89deg :)

**Q.13. **There are 5 materials to make a perfume: Lilac, Balsamic, Lemon, and Woody
and MI mosaic. To make a perfume that is in demand the following conditions are
to be followed: Lilac and Balsamic go together. Woody and MI mosaic go together;
Woody and Balsamic never go together. Lemon can be added with any material.
(Actually they had also mentioned how much amount of one can be added with how
much quantity of the other; but thatâ€™s not needed for the question.) All of
the following combinations are possible to make a perfume except:

1) Balsamic and Lilac 2) Woody and Lemon 3) MI mosaic and Woody 4) MI mosaic and
Lilac**Solution:**-first is acceptable for perfume since balsamic and liliac are given to
be present and second is also acceptable as lemon can be added with any of four
,third is also acceptable as given in question...left fourth is not acceptable
as MI mosaic is always with woody...and balsamic is always with liliac
..therefore combination of MI mosaic and liliac cant occur because woody and
balsamic are never together

**Q14: **Alok and Bhanu play the following min-max game. Given the expression N = 15
+ X*(Y â€“ Z) Where X, Y and Z are variables representing single digits (0 to
9), Alok would like to maximize N while Bhanu would like to minimize it. Towards
this end, Alok chooses a single digit number and Bhanu substitutes this for a
variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu,
the variable to substitute the value. Finally Alok proposes the value for the
remaining variable. Assuming both play to their optimal strategies, the value of
N at the end of the game would be? Note: For this type of questions: x+y-z=11
x-y-z=2 x*(y+z)=18 wht shud be the approach to do such type of prob??**
Solution:**- this question was repeated 3 times for different cases yeah tcs has
this 3 type of questions where there is x+y-z,=11 x-y-z ==2 and x*(y+z)=18 if an
integer is added to any of the above equations just add the integer to the value
of the equations...for example in this case it would be 15+18=33....(dont ask me
for explanations why this value comes for those equations..it took me some
gruelling sessions to understand that )

**Q.15**. Consider two tumblers, the first containing Water and next contains
coffee. Suppose you take one spoon of water out of the first tumbler and pour it
into the second tumbler. After moving you take one spoon of the mixture from the
second tumbler and pour it back into the first tumbler . Which one of the
following statement holds now? **a)** There is less coffee in the first tumbler than water in the second tumblers
**b)** There is more coffee in the firs tumbler than water in the second tumbler**c)** There is as much coffee in the first tumbler as there is water in the second
tumbler **d)** None of the statements holds true **Solution:**- a there is less coffee in the first tumbler than water

**Q.16**-Shreya writes 1st 100 whole num. let A and B be the num of times she writes 0 and 9 respectively,find the value of A+B

**Solution:**- First 100 whole nos=0 to 99. thus A=no.of 0's=(0,10,20,30,40,50,60,70,80,90)=10 B=no. of 9's=9,19,29,39,49,59,69,79,89,90,91,92,93,94,95,96,97,98,99)=20 A+B=30

extreme positions. who is sitting immediate right to E? **Solution:-** A D B E C right of e is c I think that’s enough questions.

**Now come to Interview Part:-**

**INTERVIEW:-**

**TECHNICAL:**- Only thing you need to keep in mind while interviewing is u should be confident while replying. And English is must…..

Ok so as I am a Electronics student I”ll suggest some topics from which interviewer asks questions:-

- DIGITAL ELECTRONICS BASIC
- DIODES BASIC
- TERMS LIKE AMPLIFIER,IC,FILTER just their definition
- C/C++
- Diff between 8085 and 8086
- Communication basics
- 1G,2G,3G,GSM,CDMA…etc just basics
- OSI LAYER MODEL
- LAN,WAN,MAN
- ROUTER AND TOPOLOGIES, TCP/IP MODEL.

Be confident while replying and prepare technical well .Don’t go in deep just take overview of all subjects.

**HR:**-
Then for HR interview you must prepare your self well .. some key questions that are
asked are:-

**Q.
1.** Strengths, weakness, **Ans**.- You should prepare your strengths and weakness a few days earlier from
interview. And u should also make examples of ur strengths and weakness. Like
when u say u r a good learner then u should be capable of giving a relevanr real
life example where u can say u was a good learner.

**Q.
2**. Hobbies **Ans.**- Don’t make fake hobbies . always make real hobbies that u actually do in
free time. Bcoz they r going to ask a lot of questions from ur hobbies part.
Like my hobbies include Photography so they asked me which camera do u
use,features of that camera,latest photo u shoot,what u do with the photos,etc.
so be prepare.

**Q.
3.** Extra co-curricular activities **Ans.**- Explain work u have done apart from ur studies.

**Q.
4.** Tell me about yourself: **Ans.**- Tell ur whole Bio data and try to bring fluency while speaking about
urself.

**Q.
5. **What experience do you have in this field?**Q.
6.** What do you know about this organization? **Ans.**- This is most important part. You should search about TCS and know latest
happenings, awards won by TCS and a little history of TCS. U can go to
www.wikipedia.org for that information.

**Q.
7.** Are you a team player?**Q.
8. **Why should we hire you? **Ans.**- Here also u need to tell ur strength. And how company is going to benefit
from it.

**Q.9.** What is your greatest strength?**Q.
10.** Tell me about your dream job.**Q.
11.** What is more important to you: the money or the work?**Q.
12.** Are you willing to work overtime? Nights? Weekends?**Q.
13**. Would you be willing to relocate if required? **Q.
14. **Do you have any questions for TCS? **Ans.**- this is also important to ask a question at last of the interview so
prepare a question in ur mind before going to interview . and never ask about
Pay scale ,working hours and all these cheap thinking's that comes in ur mind. U
can go for socialism if u like social services. And many other questions are
there. But what is more important is, to ask a question because that shows ur
interest in company.

**LAST POINT-** Finally I would say that u should prepare your self for HR interview
few days earlier by having interviews with ur friends and preparing for
questions…Remember one thing friends don’t create fake hobbies/strengths
otherwise they'll caught you. common yar they r doing all India Recruitment u
can’t lie with them .They have got experience in this interviewing field.

Ok friends I think that’s sufficient. Only thing that I would like to say is that: “SUCCESS IS THE FIRST THING THAT SHOULD ALWAYS BE IN UR MIND” Hope this file will help you. Bye.
