Another tip for interviewers: If you say you are going to call back within a certain time frame, then do so! It's frustrating, disappointing and unprofessional.
Last spring I interviewed for a job. I was told that the organization had undergone a reorganization since the job was posted and the terms of work might be altered from the ad, along with the contract length. They said the position might now be much longer term than originally believed.
At the conclusion of the interview, I was told they'd get back to me by x date, one way or another.
Fine, no problem.
A week after x date, I called back. Turns out the job no longer existed and she had "tried to call me."
I found out later that they found this out just before my interview, but since it was too late to cancel, went ahead with the interview. I can understand feeling they should go ahead, since they'd already asked for my time, but I feel they were misleading, especially about the terms and the call back time!
A month later, I was at the same office on personal business when I ran into the lady who interviewed me. She looked at me, said "Didn't you interview for the xxx job?" When I said I had she said "Are you still available? Do you want it?"
Apparently, the restructuring required that position again. She had "tried to call me and tell me."
(But I still wonder why, in all the vaguaries of electronics, that this lady is the only person who could call both my cell phone and answering machine twice and somehow fail to contact me. Hasn't happned before or since....)
I did take the job, and loved the work, although it did give me some EHell fodder from time to time!
So interviewers: Do what you say you're going to do!
