Hi,
I went through 2 rounds, one in the Binary Semantics office and the other one in the google office, it was a walkin, 1st round that was an HR round with the HR of Binary Semantics , in that round only confidence was necessary and just say it clear, she asked for my introduction and some questions from CV, then she explained me about the package that's it. After this we were sent to Google office, Gurgaon, I waited for 2 hours for my turn and the interview was quite similar to the binary one, same things about CV and my blogs etc. I got my result in 3-4 days.
