The process took 2 weeks. I interviewed at X (Palo Alto, CA) in Mar 2012
Interview
Questions were not very difficult. Solutions require good grasp of the fundamentals: e.g. binary search, hash tables, etc. 1 initial phone interview, 1 again after that, and if you pass the two phone screens, an on-site interview. First interview was pleasant, but the second one not so much. The guy doubted my running time of an algorithm and told be it was O(n^2) when it was clearly O(n). Maybe he misunderstood what I said.

Question 1
Given a number n, give me a function that returns the nth fibonacci number. Running time, space complexity, iterative vs. recursive.
Everything went fine, the first interview was an easy leetcode problem, the second was a medium dp leetcode problem. The process started on Nov 20 and ended on Jan 21. The recruiter was really nice and the interviewers the same
After the initial phone interview (this followed the standard resume review and coding assessment) I completed a series of three final interviews (one behavioral and two technical). All of these three final interviews were on the same day and over video.

Question 1
Behavioral questions were standard (resume questions, experiences within a team, etc.)
Coding questions were inverse intervals and maximum of a sliding window
After applied online they emailed an online accessment with very easy questions (saying it's optional). Got all of them correct, but no reply since then. Not even a rejection letter.

Four fairly easy questions (all of which are easy questions on LeetCode)
