I applied online via the standard process and was contacted by a recruiter asking for a short phone interview.

I was then scheduled for a short online coding test, which was pretty easy. All answers can be found on Glassdoor; Yelp should get rid of this part, in my opinion. A lot of the generic multiple-choice questions were irrelevant to my skills, interests, and experience.

After that, I had another interview with an engineer over Skype. After passing that, I had two more interviews with other engineers. One of them was actually a video interview with a coding question on video.

None of the interview questions were difficult or tricky, in my opinion.

It really helps if you know Python.

None. All questions were pretty easy.
