Whether or not you get a similar type of question this is a great theme to think about before your interview. Think back through your career or education or any prior experience and think of a situation where you presented with a very difficult situation and how you either overcame the situation or didn’t. Remember you don’t always have to win, but you need to demonstrate that you can learn from these types of situations. This is not a one sentence answer, the interviewer is looking for you to demonstrate that you have problem solving skills to work through a situation or that you can handled some ambiguity.
