Amazon Operation Manager interview questions

Applied online at Amazon Jobs website after seeing position on Glassdoor search. Was contacted by a recruiter to set up a phone interview. The phone interview was conducted by someone that had worked in a similar role. The phone interview was supposed to have a math problem, but I wasn’t asked to do one. I was contacted via email the next day that I was moving on the the next step in the process. The next step was a four person round of interviews, each approx 45 mins long , and were all conducted via the Chime video conferencing. I also had to do a writing sample submitted prior to these interviews. As stated in multiple previous reviews, all questions were behavioral based, and I was instructed to answer in the STAR method. Overall, a very comfortable experience with each interviewer and the 4 hour process passed quickly. I was told I would hear back with 2-5 business days. The next day I received an email with an offer.
