Tesla job application

Hi, I'm applying for a Tesla just to get the experience. While applying I saw a question named "Evidence of Excellence" with a 2500 character limit right before the resume-upload part. What is this question aimed for? this is the only thing I found so far: >> You may be asked for a relatively brief account of your "evidence of excellence". Tesla wants problem solvers with a track record. Show that you fit the bill. It’s worth applying to Tesla, even though there’s so much competition, but it’s not worth applying poorly. You will almost definitely be rejected. #tesla
