What you're saying is that this is a worthy use of time for people because they'll maybe move up in the leaderboards which then might lead recruiters to reach out to them.
And after all that, you have to do a phone screen, technical phone interview, a full-day onsite, plus whatever other hoops you'll be made to jump through to change jobs.
Yeah, no. Hard pass. Seems like a huge waste of developers' time.
