No idea of the logistics, however
Paid art tests.
I only speak from personal experience … if you are in this application process like we all have been at some point (and I assume the art test for a junior or a fresh student is out of school or a similar scenario), it is often like living from paycheck to paycheck at this point, maybe working 2 jobs, repaying student loans if you haven't been to school long enough, etc. Take time out of your week to do art tests that you put a lot of effort into have, with a high value The chance to be ultimately rejected can understandably be difficult.
A pre-post-test review, even if this is a no, would not only set a very good tone for the company, but would also help address the upside-down world of costly education and the financial instability of younger generations in this area fix industry. A few hundred dollars isn't for a large company, but it could mean a lot to someone who produces work for one. I would be delighted if this were normalized. (I don't know what Riot is doing, but I think I've heard that some companies do (?))
