The interviewer wants you to identify leadership qualities to see what you are looking for in a manager or boss. Here is a short list we came up with that might help jog your memory:

1) Honest
2) Good communicator
3) Good listener
4) Committed
5) Positive

Your favorite boss may not have embodied all of these qualities, but they most likely were enjoyable to be around and challenged you in some way. Give an example of something they did that impressed you, like giving you positive feedback and encouraging you when you were struggling to meet a sales goal.
