I attempted 32 questions exactly as i know the answers already… hahaha…Result was declared on the next day but i was pretty sure that my name will be announced in the list as my HR already told me that “i am done for the day and can go to hostel” 🙂 thats the phrase that i’ll always remember in my life.

I have to wait a whole one day for the results and finally TCS recruited 69 students from our college and i was one of them..yahoo!!!!!

Technical:

Frankly speaking i spend hardly 5 min in technical round and answers all the questions correctly with confidence. My technical is more or less a combination of technical and HR.

Second round starts with a funny question that whether i have a girl friend or not..:) whether i drink or not etc. again my interview continue only for 2-3 min and i was told that i am selected and can go to the hostel and sleep.

Getting job in TCS is one of my great achievements in my life.

So do your home work well and keep faith in GOD.

All the best!
