I had an awful manager who discouraged team collaboration (work independently, don't ask questions or bother others). I seriously struggled because I was a new developer and had no onboarding. Just tossed into the deep end and unfortunately I drowned. Our 1 on 1 meetings were an interrogation about all the mistakes I've made over the past week and why I made them. The increased stress of not making mistakes made me make more mistakes... Finally the deadlines were constantly shifted. Boss would ask how long something would take, I'd give an estimate, we agreed on that date. When that date arrived he'd say, "I think it shouldn't have taken this long. The other guys on the team could have done this in half the time". This went on for a few months until one day I was fired on the spot. It was a blessing in disguise! I'm at a much better place now.
