There were three phone interviews: with the recruiter, an engineer, and the team manager, respectively. All were low-key and straightforward. Most questions were about experience and skills listed on my resume, but there was also a smattering of technical questions.

The onsite technical interview took most of the day (10:45 am - 5:00 pm). All in all, there were seven rounds, including the lunchtime chat with the manager.

The coding questions ranged from relatively easy to somewhat difficult, but all were totally reasonable. I never felt too rushed or pressured while writing code on the whiteboard. It helped to maintain a dialogue with the interviewers while coding because they were all willing to nudge me in the right direction if I was unsure of a solution.

One of the more interesting questions went as follows:

Given an array of nonnegative integers that represents a histogram (specifically, a bar chart), how much water would it hold in between the vertical bars if you poured water over it?
