TDC Systems Integration interview questions

I applied online and was contacted approx. 1 week later via email to schedule an interview. After giving my availability, I did not hear back so I then called to make sure everything was still ok. After calling the organization, I was told they would contact me back to schedule a day/time. Well, I never heard back from them. Come on people, we have to do better with communication. This reflects poorly on the company.
