At a manager level, my #1 red flag is if they don’t quickly move to integrate the team they inherit.
This is different than changing things up, or even deciding who to keep.
But true managers always at least try to integrate with the team they inherit on Day 1, or at least half-way through Week 1.
If you hire a new VP and you see legacy folks on his/her team excluded in the first week, not invited to things, cut out of the loop … that’s a subtly flag. Of someone not quite yet seasoned enough to be a true VP.
You have to go to battle with the team you have. The best managers know this. Yes, you can change the team and usually should at least evolve it — but not overnight.
