The interview lasted all day and began at about 11 AM. There was a mix of programming puzzles and real-world based tests used to assess competency. The usual social and human resources based questions were also included.

It was really a bit of a mix, tough and easy. Most of the interviewers were very supportive, but some of them just came by because they were assigned to do so.

I had a phone screen with a recruiter and set up a series of video interviews with the engineering team. They asked questions about data structures and algorithms, with more of a focus on trees and sorting.
