I applied online. The process took 4 weeks. I interviewed at Fitbit (San Francisco, CA) in Nov 2018
Interview
The interview process contained a chat with the recruiter, followed by a phone screen, and then an on-site. The phone screen consisted of a discussion of an algorithm implementation followed by a discussion of past work experience, where there was some room for error on the former. The on-site consisted of four interviews, including two coding interviews, one architecture interview, and one manager interview. Overall, I felt that the interviews were fairly good evaluators, rather than focusing on getting tricks or having less useful algorithm knowledge.

I applied through an employee referral. The process took 3 weeks. I interviewed at Fitbit (Boston, MA) in Aug 2019
Interview
Small sized office (almost 200 people) in Seaport, seems very cozy. Product they are working on is brand new so that interested me greatly. Management seems to understand priorities and work is focused on doing things right instead of just delivering features.
The interview process was brutally long (6.5 hours in total including lunch). Other than that, the interviewers were all very professional and this truly looks like a fun work place to be in. Very collaborative. Benefits look great and can definitely see myself staying here for a while if I joined. Unfortunately with all things, timing was key and I had a much better offer right before I received the final package, so had to decline this opportunity.
