I think you are right that management skills, like technical skills, are transferrable across domains. Though one caveat may be that size of team and overall organizational structure and reporting relationships can be influential dynamics on actual experience and skill. I would look to evaluate the candidate's ability to help others problem-solve and set priorities (rather than just dictating), clear communication skills, and "strategic empathy". Lots of good searchable behavioral and other interview questions available online. One nice thing about management skills is that communication is a core competency in the role AND at least somewhat interrogated by the interview format. Not always the case. Good luck!
