You are right. Most teams in-fact dont hire junior devs for the fear of spending too long to review their PRs and hand-hold devs. We have been able to eliminate a lot of un-usable PRs by having a very strong internal peer review and QA process. So PRs almost certainly works, and code review goes through at-least 2 separate reviewers TBH, I think adding teachers that grow devs entirely through reviews is a great idea. We currently do give internal training and guidelines for reviewing PRs, but havnt gone that far yet.
