Academic Interview Etiquette

I am chairing a search committee right now and we are in the midst of scheduling interviews. In the interest of being friendly, welcoming, and preparing for unforeseen travel delays, I have given my home and cell number to the candidates. One of the candidates called my house yesterday. At 9:30PM. I was in bed already*, so I didn't answer the phone. S/he had also emailed asking for good times to call. I emailed back this morning and said that anytime before 9:00PM would be fine (I also happened to mention that we are two hours later here than where s/he is). I did NOT mention what time that call came in last night, because I don't want to make him/her feel bad, but I really hope that doesn't happen again. Even when we're awake, we tend to not answer the phone that late- especially if the number is unknown. I'm not even sure why this person wants to reach me or why s/he seems so intent on talking immediately, when the interview isn't for almost a month, either. One other interesting thing is that I met this person last spring when I interviewed at her/his current department! Maybe s/he wants to get the low-down, since I was trying leave. We'll see.

*I arrived at school at 7:30AM yesterday and didn't get home until after 7:30PM. My day included teaching, meetings, lunch with a friend, and attending a visitation for another friend's father. By the time I got home, I had a splitting headache and went to bed early.
