On the folly of asking the same question once

This actually frustruates me because it indicates the author has the reverse problem - caring about and evaluating a candidate based on whether they ask him questions at the end of the interview. I'm really skeptical this is a good screen for any kind of future performance. Interviewing is hard, but more often than not the mistake I see people making isn't ignoring what matters; it's failing to ignore what doesn't matter.

I've had this problem on interviews before, you get scheduled to talk to a bunch of people, serially, and end up saying/asking the same things over and over. An entire day of that is grueling and can wear down virtually anyone.

For this reason, I actually prefer panel interviews where 2 or more people interview a candidate at the same time. This way less time is wasted and the interaction between interviewers can be useful for the interviewee as well.
