3/4 step interview process, one introduction interview, 2 technical interviews, and a final interview. The first technical interview included a discussion of the React Native eco system and a PR review and the second technical interview was a system design.
The technical interview part of the process seemed rushed with little though put in to it, the PR review's code was very convoluted and made little to no sense and they were essentially asking to point things out that were incorrect and make some changes to the code.
(My advice to the company would be to actually ask people to implement something to actually see how they work)
