As said above, this is mostly a terrible idea, it will for sure discriminate against look, language, accent, gender, personality traits, and obviously race, no matter how you make your platform NOT to, people are biased when there’s no context for what your knowledge worth (like a resume or portfolio) to weigh things up and down.

I remember I saw a similar site did a similar thing for a mall hiring in my city, and out of personal test and obviously not a statistical data, I gave the same script to be said by two different individuals, one was a good looking dude, shot with a dslr camera and another was just an average looking one with a phone camera, the first received around 7 calls back while the second is none. Then I repeated the test but this time against a female with a phone a camera and nothing professional, the female received 14 calls back, same mall, same shops, and within a 3 days the test was done. It gives you an idea how the hiring process will be.

Additionally, it will reinforce the bias and obsession the new generation have with the overall look, I read a few articles how tiktok is negatively affecting that, to the point some are breaking their jaws with hammers for some reason.
