It is bewildering to me that there are companies where you don't interview with the team you will join. What if you don't click with them? These are the people you'll spend every day working with.
Do you want to do 100 interviews? An interview with 100 people asking you questions? If you interview with the "wrong" team or someone else accepts a position with that team before you do, do you want to be dropped from consideration?
That structure for interviewing is set up to try to find as many people who are {this good} as possible to hire. Once you get hired, then they'll try to figure out where you fit in. Trying to fit each person to their exactly right and best fit spot as part of the interview process makes it even more time consuming.
