I once had an interview for a job that would have been ideal for me, which is why I applied despite a rather hideous commute. The interviewer spent most of the interview implying, without stating, that the commute was too long - if that's what she felt, why did she call me in for an interview at all? - and then afterwards sent me a message claiming that the job's work hours violated the employer's work hours policy, which I don't believe because they would have checked that first. I think it was just a way of getting rid of me, not a unique tactic.
