So you will pay 10 times more salary, rather than waiting a couple of months for a new engineer to get up to speed? You must be in a hurry. What about all those other employers doing enterprise CRUD apps, are they in a similar hurry?
"I need to fill the position with the best possible person"
I assume then you are not working on enterprise CRUD or dinky mobile apps like everybody else. Are you competing with Unreal's next game engine? Or working on a rocket to Mars? Because your peer employers are NOT.
Yeah, those guys who complain about not finding candidates.
