I was contacted by an internal recruiter who scheduled an initial interview with me. An hour before she said "an unexpected, yet essential, meeting" popped up on her calendar and she needed to reschedule for 3 hours later. I cordially agreed and waited for 40 minutes and received no call. I would have called directly to leave a message, but she didn't even leave her phone number in her email signature. I sent an email in response but still haven't received anything back. The experience was so unprofessional and rather rude for such a great company. Very unexpected and disappointing.
