I failed out after the first round but it was a fairly standard 1 hour interview with two devs from the team, they asked the fizzbuzz question then asked a system design question about a rate limiting system. Interviewers were nice and easy to get along with.

Initial call with HR, call with dev team lead, 2 basic code tests to ensure I was fluent, and a final 1 hour meeting with the whole team to determine a good fir.
