I love how those openings lists super serious requirements but rarely states how much much it pays. You realize that professional with the skills you listed will not ask you for less then 100 000$/year ? I mean you are offering 5 step interview - that is some google level stuff. I hired many devs in my time and learned - to hunt a professional I need to tell him what he gets clearly and maybe even before telling him what I ask for.
Outside of Bitcoin, only a handful are available and mostly spoken for. I suspect this is why you've got people coming here trying to headhunt CTOs on the forum.
It seems they are about to be surprised

Don't get me wrong I don't have anything against headhunting here - it's great idea, but they should put wage and most important skill in big bold letters. If I was looking for CTO I would do it like this:
HEY DEVS, WE ARE LOOKING FOR THE PRO CODER FOR TRADE ENGINE DEVELOPEMENT.
IF YOU KNOW GOLANG, GOT A GOOD IDEA ABOUT HIGH LOAD APPLICATION AND MICROSERVICE ARCHITECTURE - PM US.
WE CAN AFFORD TO PAY YOU UP TO 200 000$ PER YEAR
That would have catched my eye.
