I met them on campus for an on-campus, in-person interview, and it went well. I was contacted about a week later to be flown out to Bellevue, WA, for a round of interviews at their headquarters.

I had three different one-hour interviews:

• The first was mostly conversational. The interviewer was into databases, so a lot of questions were about that.
• The second interview was more white-board coding-oriented. I was asked to solve an n-by-n Tic-Tac-Toe game. I think I did fairly well since I managed to get an O(1) solution.
• The third interview was OOP-oriented. I was asked to draw out the design I'd give a library.

Overall, I don't think I did too badly. I'm an undergraduate student, however, and the rest of the interviewees were graduate students who already had prior work experience. I think that's what ultimately led to me not getting an offer.

Can an n x n tic-tac-toe game have a winner determined in constant time?
