Pretty smooth interview process, there was 2 rounds after submitting resume. First round with hiring manager, which evaluated product sense and PM skills, and second round with engineer which was a technical interview. Both rounds lasted 1 hour each.

I was met at front desk by coordinator, and then showed around the office (was offered water, tea, coffee). I then had four half-hour interviews with different engineers. The first interview covered some systems knowledge questions, a web page design, and a simpler coding question. The second interview involved another coding question on the simpler side, and discussion about the type of project that I would like to work on. The third and fourth interviews, were a single coding question of above average difficulty.

Started process via career fair. Interview process for me was a brief set of screening questions on Python and Unix utilities (at the career fair), followed by a short non-technical phone interview, an online coding challenge, followed by the onsite. Onsite interview: under NDA. Had multiple rounds, and questions were fair, of varying difficulty. Touched on algorithms, complexity, testing, implementation.
