A résumé lists your wins. An interview finds out how you handle losing.

A list of achievements tells someone what went right and nothing about what you are like when things go wrong. That is the part they actually need, because most of any job is the wrong part. So the questions circle around the failure: the project that collapsed, the deadline you missed. They want to see how you behave without a win to stand on.
Pick one thing that genuinely did not work for you and get honest about it in four sentences: what happened, what you did, what you would change. Practice it out loud once. Having that ready turns the worst question into the easiest one.
How would you describe your worst failure to a stranger?
