We all need jobs to survive (unless you're Jeff Bezos or similarly moneyed), which means a lot of us have to suck our feelings in through our teeth during the interview process. While it's par for the course to feign greater enthusiasm than you feel towards a job, we all have the lines we will not cross.
There are times when the emptiness of your wallet simply doesn't surpass just how sketchy, bad, or unappealing a job seems. In most cases, if a potential employer can't even properly court you during the job interview, then it's a sure sign the job itself is going to be a bad time. In these situations, exiting promptly can be the best move, even if it means prolonging the job search.
Refusal to discuss salary…this was interview #3.
Years ago, I went to an interview, and sat down with the man who was to interview me. Sat in silence while he read something on his computer for a few minutes, then waited for a minute or so while he looked over my resume (it was a small business, he is the same person who called me to set up the interview and he’d had the resume for a few days.)
