I'm in the process of interviewing for senior and staff front end positions. I've done several multi-hour take home projects now and a couple were rejected with generic rejection messages. It's pretty insulting to be frank. Spending 2-4 hours on likely valueless work is a substantial amount of time relative to the week day. If I've spent the time making the project and they've spent the time recruiting me and reviewing the project, the recruiter and reviewer could spend 5 minutes sending constructive feedback.

Anyone else share in this frustrating experience? Have you successfully asked for feedback before?
