The interview process was much longer than other companies - two months from initial interview to acceptance. I had one phone screen and 5 on-campus interviews which each lasted an hour. The on-campus interviews were the hardest of any company I've ever interviewed with (including many small companies, Microsoft, and Facebook).

I applied online. About two weeks later, I got the first phone interview. I passed the first phone interview. But I was rejected by the second phone interview. The interview questions are all about the algorithm.But they care a lot about the edge cases and how you think about these questions.
