<p>Well, my assumption would be that a very young interviewer will be either understanding and personable or inexperienced and as nervous as you are.
I would think that 30 and 40 year old interviewers are not uncommon. Interviewers in their 20s may be rarer, because recent graduates tend to be busier.</p>
