Datapoint here, I didn’t say the truth at my exit interview. I left because I was angry my team lead wouldn’t help me reach a new level in my career, but I pretended it was for higher pay. Blaming it on my manager would have been useless and closed doors if I wanted to rehire in the higher position. Saying it wouldn’t have given them an opportunity to fix it, because I needed to learn skills to become a team lead, which I hadn’t, so they couldn’t have just promoted me.
