Have you ever had to interview someone on short notice? Ever felt like you didn't know what to ask, or how to evaluate the answers? You're not alone. Unfortunately, what most managers do is "wing it". And that's more than just ineffective - we think it's wrong. The danger of winging it is not just that you feel uncomfortable, you look bad, and you don't get good information upon which to make a judgment of the candidate. The real danger is that the candidate can tell that you're winging it, and that reduces your firm's chance of hiring the best candidates.
