The Impersonal Touch

So I didn't get a job I applied for. I'm not bitter. Really. I'm not. But I am annoyed at the continuing way in which we our treated in the procedure.

Kept in the dark for weeks, then suddenly called for an interview from a personal email address, everyone is 'matey' and friendly, and then abruptly sent an impersonal email from a generic address (human resources) telling us we have been unsuccessful but without any indicators as to why.
