After I applied, the process was a recruiter screen, then a manager screen, and finally an in-person onsite in their New York office. The onsite was comprised of four rounds: coding, system design, another manager, and a behavioral. Everyone I talked to was very nice, the questions were fair, their new office is cool, and I got a good impression of the place. I'm sad I didn't get an offer. It wasn't a total disaster of an interview, but there were places I could have done better for sure (taking the hint they were giving about scaling in the system design round as one example).

Recruiter reached out on Linkedin, first step was a call with a director of engineer to get a feel for what company was working on, then a two hour online coding and problem solving test administered through ByteBoard. In person interviews were a pair of their engineers at a time asking a pretty collaborative question with some white board designing and then coding on a laptop. They seemed to really make a lot of effort to ensure the interview process is meaningful reflection of the skills they want. overall positive experience
