Sounds like an interview question without a specific scenario! I see scenario based questions are common now, such as:
-How would you deal with a team lacking motivation?
-What would you do with a Product Owner directly assigning work or always asking for more work to be done in the middle of a Sprint that has nothing to do with the Sprint Goal?
-How would you deal with a reluctant team member or unhealthy conflict?
For a Scrum Master I think the good judgement and logic are the steps you took to coach, teach or facilitate and knowing what method is appropriate. Its always good to have some examples of how you are commercially aware too, stakeholder management is coming up a lot in interviews!
