Correction: DO practice interviewing. But don’t wait until opening night to stage a dress rehearsal. If you are looking for a promotion, interviewing for a new job or making a sales call, act like your presentation makes a difference, because it does. And because it does, when you are in the hot seat, interviewing for the job you really want, you want to be ready. So you have to practice. But don’t practice interviewing during that critical interview. By the time you get to the big stage, your side of the conversation should be so well rehearsed that it seems totally off the cuff to the person across the table.
