4 rounds - Recruiter, hiring manager, panel interview, AVP. Technical questions throughout and determining if you're a fit to work with that specific team. They can move fast, I had all interview within a week.

There were four rounds of interviews. The entire process took about 6 weeks. The first was a phone screening with a recruiter, then I met with teammates, then the hiring manager (probably the hardest), and lastly was VP of engineering.
