I heard back after ~3 weeks and had the recruiter phone interview. After that, I had another phone interview with a product question, and submitted a take-home assessment and then had the 5 onsite interviews. Overall, the interview experience was positive. I pretty much relied on Product Alliance's Uber PM Interview course, which helped a lot with what to focus on during each interview round. I mock prepped most of the questions that Product Alliance provides, which was very very helpful. One of the questions I was asked was directly from that list.
