Company : Tata Consultancy Services (TCS) 
Mode : Walkin held at Anna Univ, Chennai 
Date of written test : 29th Aug.
Date of interviews (Tech & HR) : 3rd Sept 
Date of Result (telephonically) : 9th  Sept.

 

Rough Estimate :

Total participants : 27,000 (for 2 days)

Total selected for technical intrw : 1000  1200

Total selected for HR intrw : 300  500

Rejection % in Tech intrw : 40 %

Rejection % in HR intrw :  4 10 %

 

Written test :

 

Prepare from previous papers. Its of the same pattern.

Prepare wordlist from Barrons. There was no psychometric test.

We had only 1 and a half hr to complete the paper.

For quants, we had to write the answers and were not of multiple 
choices.

Logical questions were bit tough.

Main problem is the time shortage to complete it fully.

 

Interview :

 

There were around 8 - 10 panels for tech intrw held at TCS, Karapakkam, 
Chennai.

Environment was excellent.

People from TCS were very soft and had a cheerful face.

 

In my panel, two persons of age around 35  40 yrs interviewed me.

Tech intrw was held for around 55 min. 

Slightly drilling but easy.

After clearing tech, I attended HR where one young man interviewed me.

It went for half an hour exactly.

Most of them were only personal questn and some tech Qs.

On my time slot, 5 ppl attended in that same panel and only 2 cud get 
thro.

 

For another friend, the tech held for just 10min.

They asked 2 gen. Qs like where he is from (Ambattur) and how he 
reached that office.

Then 2 tech Qs 1) Shannons theory ? Ans: I dont know

2) Diff betn up85 & 86. He told correctly.

He got selected.

 

So, it depends on ur luck to get a good panel.

-----Thats all abt my first interview experience at TCS-----

 

Some tips :

 

1)      Give a sweet smile before them and also greet them saying nice 
to meet you       ( u know 1st impression is the best impn).

2)      They mainly see ur level of confidence. So be bold and 
determined.

3)      Even if u dont know the answers, be polite and say u dont 
know but not frequently.

4)      Dont bluff anything.

5)      Their next Q will be from what & how u ans the prev Q. So be 
careful with ur ans. The way u ans the Q is very imp.

6)      Dress code should be formal but dont ornate much.

7)      Be simple and dont act so smart. This is imp.

8)      Ur ans must be lucid and precise.

9)      Know everything abt TCS. This helped me a lot in my HR round.

10)  Take care of ur body language.

11)  Use a mild accent and be fluent.

12)  The most most imp.thing is try to speak openly / politely. NO harm 
even if u hit some jokes related 2 ur ans. This is what big cos. expect 
as a gud qual. of a team member. Uve 2 be dynamic.

13)    Dont forget to take Xerox copies of ur marksheets, certificates 
and reports. When 1 person was Q me, the other had a look @ my 
certificates I had from school level. This is added adv.

14)  While ans ur proj Qs, show ur report and ans. This creates a gud 
impn.

15)  Stay cool and before getting-in to intrw, think u r a TCSer.

16)  The very basic thing is that be clear with ur ideologies and ur 
ambition and in what way ull be useful to the co.

17)  Whatever u r writing in the appln / resume, be strong and clear in 
that. Q will be mainly from that. 

18)  Give imp to even hobbies. Only if u r strong write it.else dont.

19)  For written test, prepare mainly from previous papers and also 
practice word power from Barrons. Thats enough.

20)  Dont loose ur confidence for any reason.

 

 

 

I'm awaiting for the offer letter

can update ourself.

 

All the best for TCS aspirants ! !! !!!
