Conducting an inteview is always a part of evaluating your own managerial skills. Its not only the test of the candidate but its a test of you ability to judge a right candidate for your company as well.
Most of the people conducting inteviews, found to be over smart or always trying to make their own impression on the candidate. That's not what you are sitting on this side of the table. Rather you are here to find a talent, not to prove your own. One point that one interviewer should always keep in mind is they should always look for talent, not experience only.
