I've been getting a ton of interview requests from "expert insight" companies asking to pay me anywhere from a few hundred to a few thousand dollars for an hour long interview, as I have "expertise" that make me a good fit for it.

While this sounds like something I would love to do, it feels a bit fishy, especially when they start saying things like I could get paid $5000 for an hour of work.

Are these types of arrangements legitimate? If they can go both ways, how do you tell a legit one from a scam?
