Telephone Interview : I was asked to write a code then walk through the code. in Person : I had 10 rounds. In all rounds, I was asked to write code. Either algorithm of simple c function or to solve complex word based puzzles using algorithms. I cleared 9 rounds. I had last round with the Unit Head. He gave me a puzzle, which I think i messed up. I did not make it. Later My recruiter told me that I was rejected not because of code, but because i did not ask enough questions.
