Perhaps, but PIPing and firing is bad for the employee, bad for the manager, and bad for the PIP'd employees teammates. PIPs don't happen immediately; it might take a month or two before it's clear to a manager that a new employee isn't performing to the expected level.
So I think I'd rather have a candidate spend 7 hours interviewing if it could save months of pain for multiple people later.
(This does assume, of course, that the 7-person interview panel actually does decrease the incidence of hiring-the-wrong-person enough to be worthwhile. I don't know if that's actually the case.)
Out of all the things I think are wrong with tech jobs -- and with employment in general -- I don't think "I have to interview with 7 people instead of 1 or 2" even cracks the top 50.
