I was contacted by the manager, via phone. During our conversation we agreed on a set interview time, at the seatac airport. He sent an email confirmation, I arrived at the airport said specific location, a few minutes ahead of time, texted him to let him know I was there. No response. 7 minutes after our said interview time, I called his phone. He asks me to wait another 25 minutes, as he is "running behind", at that moment, I realized that my time was not valuable, nor was my gas and money spent to park. The airport is not an easy in / out. It takes additional time to park and walk to. Therefore, I decided not to wait. My time is valuable as well as my effort, and money spent to get there and pay for parking. I understand that things can happen but I felt this was very unprofessional, not what I am seeking. He should have called me in advance to reschedule.
