You’ve narrowed the field to three or four superb candidates. To choose the best one, give each of them a tour of your facility. Watch how they meet and greet your colleagues. If they sound “up” with executives but less enthused about the mail room clerk, that’s a red flag. It’s also normal for a top candidate to ask questions and be slightly overwhelmed because it’s tough to process so much information at once. That’s why candidates who profess complete understanding should raise your guard.
