Here's the thing, and I'm open to thoughts here. But I've found that candidate A can be a great fit for company B, but a terrible fit for company C. I think a match is way more subjective than folks tend to give it credit for, and a rating system (like Uber) makes it seem more objective than it actually is. It works for things like Uber, where you can have hundreds of ratings very quickly, and so it converges on a natural truth. But with fractional clients, I think the N is so small that there's might just be too much noise.
Thoughts?
