The "smoker" has been getting a lot of bad press and deservedly so. See here for some of the relevant links. I have a proposal. Either members of the interview teams should not attend the reception/"smoker" or they should refuse to talk to prospective job candidates during the reception. They should, then, let all their interviewees know that they will not be attending (or talking to them during) the reception. This is what I would propose to my department if we were conducting APA interviews.
I take it that there is no point in getting rid of the reception. What's problematic is not the reception itself; rather, it's that many schools treat the reception/"smoker" as an extended part of the interview process. We should put an end to that, and it seems that my proposal would do that. What do others think?
