Round 1 - Talk to HR
Round 2- Talk to Engineering Hiring Manager
Round 3 - Do a take-home test and then a code review followup
Round 4 - Talking about their culture and product manager interview where you talk about how to scope out a feature.
It was an easy process. Didn't get an offer though and received no real feedback. Just a standard template rejection message from a no-reply account.
If you have to do multiple rounds of an interview and that includes project work, I expect some feedback.
