It was the first time I was attending interview of a mass recruiting company. Although I got call from Capgemini to attend the interview, but it was a walk-in and a huge number of candidates were present. I felt like to leave as soon as I reached. But after travelling for 20 kms, I thought it is better to waste few hours more and attend the interview. Waited for around 1-2 hours for the interview. The interviewer (an architect) was quite good. Although I felt that she was not having much knowledge. The interview went for like 30-45 minutes, with very easy questions. She was quite impressed by my personal projects which I did, and mostly asked questions on them. She wrote "selected" on the review paper in front of me. And also spoke to HR, that I have a very strong knowledge (in front of me). Got a mail to submit documents the very next day, and then the most unexpected thing happened. I had asked for 40% before coming to interview, and they agreed for it. But after getting selected, I was told that, they cannot offer me much, as their salary bandwidth is equal to my current CTC. I told, I cannot negotiate below 30%. And that was it. Wasted a full day, for Capgemini interview.
