Have you ever been in a position to hire employees?
Yes, making employment decisions has been a routine part of several of my past jobs and my current job as well. I have always valued the opportunity to have a say in staffing my own department. As you well know, hiring people is a real judgment call, and eventually you develop an insight―even an intuition―about who will work out and who won't. Personnel decisions are people decisions, and everyone is unique. Hiring them properly isn't really a science. It's an art―just like motivating and managing them.
(If no, but if you have related experience:)
I have never been directly responsible for hiring, but in many cases I have been asked to speak to prospective employees and later give my opinion. My superiors valued my insight and my knowledge of the job requirements in making their selection. In that way, I've indirectly hired some of my best coworkers.
