This is a pretty good list. It's a bit self-serving on the technology questions as well as the general line of questioning for TestMunk (understandably).

If you are really hiring a QA Manager, also consider asking them about their team structure/building philosophy, elaborate on the technical requirements for those roles, if they have experience developing a testing process that works with your company/group's development process. What experience they have with problem hires and how they've dealt with them.

This is really a list of questions of a principal test engineer. A good manager should be able to answer them, too, but it's far more important that they can make a group of QA engineers perform well (otherwise you should be hiring a QA lead).
