They have you interview with the hiring manager, then do a takehome project you have one week for then they'll have you do a 3 hour interview. The interview process wasn't difficult just too long in my opinion and excessive but the interviewers were all nice.

Behavioral/informational phone screen -> phone screen with the manager -> easy online coding challenge -> onsight interviews with a mix of easy technical and behaviorals from different teams -> onsight to meet the rest of the team. Everyone was extremely friendly and made me feel right at home. I really enjoyed the way they spoke about the company and the freedom they give employees to take agency on their own projects. The interviews were more conversational probing questions about teamwork, personality, and work philosophy. I don't think so many were needed, but they were so friendly that it wasn't a bother.
