There were six rounds:
1. Recruiter screening
2. Hiring manager, portfolio review
3. Senior product manager, behavioral
4. Senior product designer, behavioral
5. Head of product, behavioral
6. Chief brand officer, behavioral
Overall, everything went really smoothly and each round was scheduled quickly in 1-2 business days and the recruiter kept on saying there was "positive feedback" from the team. Then, after the last round I didn't hear an answer for three weeks. Turns out, they hired someone who was a personal referral instead. I asked for feedback after receiving the rejection email but there has been no response.
