i once got through the entire interview process (salary negotation etc etc) interacting with the person i thought would be my boss. i specifically wanted to the job because i liked this person. but when i received the offer letter, i discovered that someone else would be my supervisor -- it definitely caught me offguard. and turns out it ended up being the worst job i'd ever had. i wouldn't call the supervisor bait-n-switch a red flag, but now i'm now hyperattentive to even the tiniest of hiccups during hiring. surprises during the interview process can equal surprises on the job as well.
