doesn't everyone kinda do that already? on every interview I always try to get a hint on how it is to work there... and if the vibes are not there I just stop.
Once I was getting weird vibes in an interview, there was one "boss" and two "engineers" (quotes because they were probably all engineers, just that the roles were quite clear) and I interrupted the interview to ask the engineers "are you happy working there?" and they basically didn't answer with words, but their faces were very transparent... so yeah, I didn't "call them back" lol (or rather the next time they did I turned them down)
normally I'm a bit more subtle though.
