Can you rephrase this question
What is the question and I can help
Look back at a time where you really screwed things up, but you learned something
then basically just tell them a time where you screwed up and survived
(you could just take the time that you messed up and make up a lesson you learned, you don't actually have to learn it, it just has to sound believable)
I would choose to interview Katie Ledecky. I would ask her what advice she would give someone wanting to pursue something new. I would ask this question because Katie has a lot of determination. She also puts a lot of effort into everything she does and I think she would have good advice.
(hopefully this will help you in some way? haha)
