To add to this: it's very unlikely you have a company that knows how to manage a dream employee efficiently. Or just regular employees really.

Ask yourself this when hiring: you genuinely have a series of actually-actionable tasks ready to go for the new hire? Do you have the right resources on hand who understand that a part of their job is to answer questions about those projects from the new hire (and it will probably be a whole lot of stuff)?

The answer is going to be that you probably don't, and so whoever you hire, no matter how good they are, your company will just never know.
