Written test consisting of 10 questions (reverse linked list,bits set in a byte,least common ancestor,some db and caching design). One coding test on the computer .Three face to face rounds. I think they have pretty much standard interview process. Interviewers come prepared with those questions and if you answer them correctly then you are done. I'm saying this because they were asking about different software development life cycles,architectural patterns etc which most of the people don't use in their day to day work.

This is irrespective of the experience. Would not suggest an experienced guy with 5+ years to attend. They don't have a big setup, so growth would be stagnant. Most of the people seem to be recent college grads.

Reverse a linked list, surprisingly every interviewer is interested in this silly question
