He asked me two questions, they were both about how I would fix a branch with low morale and engagement.

I said I would interview each employee and get a feel for all the dynamics, start with the low-hanging fruit and see if the employees have any suggestions for improvement, and then manage accordingly from there. He didn't like that I wanted to ask the employees for improvement ideas because that was "my job" and he suggested I may have to "fire everyone and clean house".
