I had 2 promising interviews Monday, last week. At the end of the interview both of these principals said they cannot offer me a job yet since they're waiting for the personnel to formally resign. I did send them a thank you e-mail but did not get any response. The first principal did a reference check a couple of days after the interview (my current principal told me and I haven't even told her), but I haven't heard anything back. The second principal said she will contact me for a second interview with the team but have not heard back from her either. Why would they interview if they have nothing specific? Is it normal for principals to interview without an advertised position? Does the reference check mean anything? I am just so anxious with the waiting! When is it appropriate to send a follow up e-mail?
