•What’s your leadership style?
Also, how do you like to be led?
Asking both will show you the truth of how they’ll lead you.
•If you have aspirations to grow yourself, ask them how willing they’ll be to cross train you once they have their feet under them.
•Ask them what positions they’ve held. I hated working for PMs who never worked as LC or APM before holding that role. There’s a lot about what they demand of you that they don’t understand themselves.
•Have they ever accompanied maintenance on work orders? Your maintenance team will thank you because, if they have, it means that they also understand what they’re asking of that team and will have reasonable expectations for turnaround times on work that seems simple, but isn’t in actuality.
•What’s their proficiency with excel. Seems stupid but I’ve had a lot of managers who didn’t know a lot about it and they were responsible for monthly reporting. Ended up falling to me (but no one knew).
