I’m confused by your response. You expect the candidates to show code from their current/previous employer ? Or side projects that most people aren’t allowed to do by employers?

No, not previous employer, of course (unless open source). I expect candidates to show code they worked on in their own projects. That is, if they have any. Having any not just forked and click deploy projects in itself is a signal, that is worth looking into.

If all their previous employers don't allow side projects (must be in US or something, where employees don't have rights), then they should pay accordingly more to balance that restriction and loss in experience.

Which employers don't allow side projects? Not every side project has to be a SaaS hustle with Stripe billing.

My employer definitely doesn't own all the code I write in the evenings and on the weekends on my own time. Does yours?
