Meta Content Designer interview questions

Was reached out to by a recruiter. Had a good initial conversation and then had a video interview with a member of the team, talking through my portfolio. Made it to the exercise round. Was contacted shortly after I submitted the exercise and was told they were no longer moving forward. The feedback regarding the exercise was very vague and said the things that were lacking were all things that I feel confidently I had done well, so it was frustrating.

The interview process was a video screen with recruiter followed by video screen with content designer, then a written exercise, then an onsite interview with 3-4 people, both individually and together.
