Three Interviewers, 20 Candidates, One Hour

A client of mine recently had a residency interview that went something like this:

1) Introduction of the program (30 minutes)

2) Hospital tour (30 minutes)

3) Round robin interview session (60 minutes) 

There were three interviewers who interviewed roughly 20 candidates in only one hour. How can anyone make a judgement about someone if they spend, literally, only five - 10 minutes "interviewing" them.

I will revisit this topic later in the season as I gather more data to see if  this is a trend. Have any readers had similar experiences? Would you like it if your resident physician was chosen based on only three, five minute interviews?
