Multiple interviews. First was a 30 min phone call with a recruiter, then 30 min call with the hiring manager. After this I was set up with a "super" day, consisting of four zoom interviews lasting 45-60 min each. One of this also included a presentation over essentially anything I wanted, just to show my abilities to present. These were with other members of the team and another with the hiring manger (the one that had the presentation). Then a final interview with a SVP. Can definitely see how this could be viewed as a waste of time if you did not get the job, as overall I spent at least 6 hours in interviews, with the super day being an entire day with how they were all spread out. However, I do see the importance of multiple members of your team getting time with you to see if you not only have the knowledge but a good "fit".
