I'm fuming.
I had scheduled an interview for a bartneding position at an upscale hotel (chain location) for this morning at 10. At 10:15, the interviewer came out to the lobby and called someone else's name. The desk attendant I'd checked in with came over and said “It looks like she's double booked you. The interview will take about 30-45 minutes, you're welcome to wait or I can get you rescheduled.” I gave them a firm but clearly not happy “Please tell her I'm no longer interested” and bailed.
For a job market (US) apparently starving for workers they're doing a great job of making us feel unwanted.
