My favorite job interview question to ask is "what do you do during downtime?"
If they say things like "cleaning, restocking" etc, that's a green flag. Normal busywork that's unavoidable and reasonable to expect during downtime.
If they say "we don't have down time" that's a yellow flag. That means they want you to look busy all the time, even when there's nothing to do. This will drive me insane as I dust the same shelf for the fourth time in a week
If they say "there's always something to do" but don't SPECIFY, that's a red flag hard stop. They're understaffed on fucking purpose and you are about to have your soul sucked from your body by this company. do not walk, RUN for the exit. Every time I get this answer, I've ended up with the "watch you like a hawk" type manager that annoys the hell outta me.
Also interviewers really like when you ask questions at the end of the interview. It makes them think and engage with the process more, which makes you more memorable in general. My go-tos are 1: how long have you been here? and 2: what's your favorite thing about this job?
