Thank you

I’ll throw my hat in. Get an idea of what his goal is, ask him to lay it out in steps. Tell him you’d like to focus on just one throughline before you move to the next. When he overwhelms you let him know that it’s distracting.

Most importantly though, start working on your resume, because you’re working at a company that refuses to manage expectations and does not support you. If one Engineer is causing high turnover like that and management doesn’t care, that’s a big red flag.
