I'm on a bit of a rampage about interviewers who don't bother to send candidates notices of rejection after a candidate has taken the time to interview with them.
You put hours into preparing for the interview. Maybe you buy a new suit. Maybe you drive several hours to get there, spending gas money you don't really have or taking a vacation day to do it. Then you sweat it out through the interview itself. They tell you that they'll notify you of their decision in a week. And then ... nothing. It's like you don't exist to them.
This behavior is inexcusable -- it's callous and dismissive and lacks any appreciation for the fact that the candidate is anxiously waiting to hear an answer -- any answer -- and keeps waiting and waiting, long after a decision has been made. It's just not that hard to send a quick email, even a form letter, letting the candidate know she's no longer under consideration.
Employers owe interviewees a response, period.
This particularly pisses me off because sane job seekers aren't going to call employers like this on their rude behavior, lest they burn their bridges with the organization. So employers get to act like this with impunity, and the rare person who does complain about it is generally dismissed as naive or crazy, simply because no one else does it.
I'm seriously thinking of offering a service on this site that job seekers could use to generate an anonymous letter to the employer, telling them how rude they are. It would be a public service: the Ask a Manager You-Suck-As-An-Interviewer Automatic Letter Generator ® .
