After 8 hours total interviewing at one company, I kinda feel like I was hired and fired in a single day
WOW! That would very exhausting.. is this norm these days to have full day interview sessions?
Northrop Grumman had a (wasteful) 8 hour "college day" that was an hour of technical interviews, 4 hours of propaganda, and 2 hours of arbitrary fluff like team building games among the applicants.
The ~5 or so on-sites I've had apart from NG were 2-4 hours.
