jerks can slow you down drastically. worked with someone who was a genius, but couldnt move in a direction until he proved everyone wrong. it felt like every decision took hours to move on. even low impact ones.
...you do know you can reject the position, correct? You're not obligated to take the job once the interviewing process has started.
I’m didn’t raise my voice or curse or anything like that. I just said “this isn’t a good fit. Thank you for your time”, got up, and left.
