Tesla Sr. Project Manager interview questions

Recruiter screening, 30 min with hiring manager, 30 min with a team member (case interview), then onsite panel with 30 min presentation, then 6 rounds of 1:1. Received verbal offer 2 days after onsite. Tried to negotiate for leveling. Recruiter asked for an additional round of 1:1 with a high-level executive. Agreed to interview the next day. The next day, a few hours after the interview, recruiter communicated that the offer was WITHDRAWN. Recruiter said hiring manager decided to hire more senior candidates.
