It's a panel process, with a specific focus from each panel member so while there are several interviews they are deep on a single subject rather than a broad discussion.

Recruiter screen > hiring manager > case > cross-functional partner round > leadership interviews round. Was rejected by the system after spending too much time preparing for the case study and presenting the case. Got the automated email rejection and was very sad about it, then put it behind me. Then recruiter reached back out to re-engage in the interview process. I was very surprised. Found time to do a call, was kept waiting for 15 min for recruiter to jump on. Was asked if I'd be interested to proceed to the next round. Said yes. Scheduled next round super fast. Then was again rejected a few days later. All in all, the people were very nice. I think in terms of processes and systems a lot can be better to ensure a more positive candidate experience. There were attempts at transparency, but more kudos to the effort than result. If the company culture reflects the interview process, my take is that the company at times struggle with effective decision-making, tend to overthink / over-engineer their processes, and maybe too collaborative. The whole thing left me slightly disoriented, but the pleasure was all mine.
