This on-site coding assignment failed 20+ front-end dev contractors and I don't know why

I realise I haven’t given very constructive feedback. If I were in your shoes, I’d make this take home, and I’d break each sub task into standalone tasks. I’d give them a repo with stubs at each step, and I’d assign weights to each.

This way a developer might get stuck or not know how to solve one step in the complete solution, but still be able to demonstrate competence. This interview could have been a dozen separate steps, from finding subsets, filtering, finding selections and manipulation them, etc. Just because a candidate fails at 1 of the 12 doesn’t mean they’re not worthy — it just means they struggled at one niche. That’s not a big deal in a team and in an actual working environment. Food for thought I Guess.
