This is too general. So I'd select 1 past work experience. Then make sure you understand what the interviewer is looking for, this allows you to structure your response within these areas, and highlight them. Then, define the responsibilities first for the role. Then, list what I achieved Then, list a few failures, we are all human, but ensure to list , why you think you failed, what you learnt from them and how you got better by stating a couple of subsequent similar experiences where you achieved better results thanks to the lessons of the previous failures. Make sure to personalize the description to make them about you, as the interviewer wants to know about you.
