Discretion abt written Selection Process

Written Test

Prepare from previous papers. It's 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.


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, Shannons theory? Ans: I don't know and Diff betn up85 & 86. He told correctly. He got selected.

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