BS. The could have walked all over her and tell her a pile of shit was roses. She didn’t even know the right questions to ask. Total incompetence. It really isn’t her fault. Her ego got her the job. Probably all of her jobs and she was lucky up to the point until she wasn’t.
You are both wrong. Hire for management, hire team and trust team to do work. Worst thing is a micromanaging manager that thinks they know the work, yet haven’t done it in years. I train program and project managers and this is a recurring problem and shortcoming of many job reqs. You want a manager, you hire a manager, you want an engineer, you hire an engineer. These are two very different skill sets.
