I think it’s a huge mistake to delegate hiring, especially the hiring of key seats.
If you must delegate that job, remember this axiom that I’ve found to be invariably true:
A’s hire A’s, B’s hire C’s
I’ve heard this attributed to Steve Jobs, but I think he was quoting Donald Rumsfeld, former Secretary of Defense in the U.S. (who was probably quoting someone else!)
Anyway, it’s the truth. B’s will never hire an A player. For starters, they’re threatened by them. They find them too aggressive, too keen. B’s have no interest in being pushed or upstaged by a subordinate. But they typically don’t hire another B player either. They prefer the C’s. The C player looks to the B with wide, innocent eyes, amazed at their mediocre productivity, compliant, easy to lead, eager to be mentored into a career of sub-par performance (on your dime).
And what is the main thing that drives A players out of your organization? Toleration of B and C players.
Do your own hiring, or make sure that another A player is in charge.
