OT, but what’s the rule about following up on job interviews? I did an online interview last Tuesday and have a thank you note for the manager that sent me the invite to interview in the first place, but I’m not sure if I should send it.

The interview notice said that I had 72 hours to do the interview and that I’d hear back 2-3 days after they got my interview back. By that timetable, I should have heard back last Friday. Would I be out of line just sending a generic “thanks for the opportunity, looking forward to hearing back” note?
