And even if someone could get time off drive times a month to work "provisionally" at a different job, I can't imagine they'd typically be as productive hopping back and forth at either of them compared to devoting all their time to one. Sure, maybe the prospective employer would be circumspect enough to judge someone based on the correct signals of stuff like whether they're asking the right questions, showing capacity to learn and grow into the role in the long run, etc. rather than strictly judging their output, but being smarter about what you're measuring instead of blindly checking off boxes is also an option in traditional interviews, and plenty of companies still don't do that, so why would the expectation that the lazy approach of only measuring results wouldn't end to happening with this as well?
