If the interview is competency based, remember that companies often go by the so called STAR method and keep that in mind.
STAR stands for Situation, Task, Action, Result. So if you are asked to describe managerial skills, pick a situation, describe the task / goal, talk concretely about what action YOU took (not team members, don't say we, say I) and explain the result.
Works everytime, because it structures your answer.
