That smells very much like a scam to me. Unless you're at an elite level, nobody is going to be cold-calling you with a $5k/hr job. And if you are at that level, you know it already and the people cold-calling you are people you already know about. My rule of thumb for telling scams from non-scams is that non-scams won't be dangling the promise of money in front of you like that. If the position is legitimate, it sells itself. Even just being cold-called is a bit of a red flag. In my experience, the best defense against scammers is to develop your own network that includes trusted recruiters, lean on that network, and ignore cold calls. Or, if you're really tempted by a cold call, run it by people in your trusted network first.
