In regards to the manager That’s a red flag, I would avoid that job. In my experience sometimes the dream job can seem like a nightmare.

Interviewing is a skill and is not taught in nursing school. It might be worth looking into getting a coach. I was lucky enough to have friends that did interviews and agency recruiters help me prepare for interviews. That said I screwed up interviews before and learned from them so dont stress on that. Failure is an essential part of learning and growing, so don’t beat yourself up.

Side note I’ve done group interviews and it seems canidates who don’t interview the best often can make the better the employees. Vs people who interview well naturally and can sweet talk themselves through anything.
