The only reason I called was because they stiffed my the reimbursement for travel expenses which they had agreed to pay for. The HR turnover was so high that everyone I had talked to before the interview was gone by the time I put in for the reimbursement.
Clearly things went your way if you didn't get the job in that environment.
Funny story about that, I'd set up a macro to fire off said email with one keypress. Finishing up a phone screen that went horribly, I thanked him for his time and all the other niceties, and pressed the key right as I was about to hang up.
"But wait! I have some questions for you, too!"
Cue the longest 5 minutes of my life.
After reading some of the comments here about candidates who want to debate the interviewer's decision, it seems to make sense.
