What I'd tell a coach who's about to hire their first team member for sales.
Hire for listening. The best setters and closers I've worked with ask a question and then wait.
Give them your words before you expect theirs. Recordings, old DMs, the questions you always ask.
Decide what "qualified" means before day one, in writing.
Review their conversations every day for the first two weeks. That's how you both learn what good looks like in your business.
And give them one number to own, one they can move every day.
The rest you figure out together.
Write those first two weeks down as you go. That document trains your next hire.
When a prospect says "let me sleep on it", say:
"Of course. What will you be thinking about tonight?"
It's kind, and it gets you the objection while you can still help.
