Keep a pool of potential employees under the watchful eye of somebody who's responsible for hiring. Evaluate your recruiting team in terms of how well they keep the bullpen ready. Push harder for diversity. Make certain you're spreading your net wide enough to find those high-potential but different fish who generally don't swim in the streams near you. Ask your HR group what contacts and periodicals they're using to interest potential hires.
Most interviewers talk way too much.
It's been said that being a leader is like practicing psychiatry without a license. That may be more true in hiring than in any other part of the job. Your legacy will be set, after all, by the teams you choose to accomplish your objectives. Traveling is now probably safer than ever. I'd prefer to stay close to home.
