Really expected more up front from the company for being a potential new hire. Upon finally being scheduled a day and time for a telephone interview ( minimum 5 emails back and forth ), I was looking forward to discussing the position and how my skills and experience would be a good match. 10 minutes after the scheduled call time I was contacted and immediately told the interviewer was 'Double Booked' and that he would call me back in 10 minutes. 1hr later, still no call back.
Extremely unprofessional and rude. I set aside time to take the call and prepared myself to discuss my skills and learn more about the company and how they operate. This I would say is a bad first impression.
Long story short, I will look elsewhere if a 30 minute call is so difficult.
