Barrett Business Services .NET Software Developer interview questions

Not really sure how their interview process goes. Was scheduled for a initial phone screen but less than two hours before the call was told that it was being cancelled based on the say so of someone at the company. No idea why and no explanation provided. Wonder why if I was qualified before and they set up the interview but something suddenly disqualified me it would have been nice to know what that was. Pretty unprofessional way to handle this as at the very least I would have liked to have spoken with them about the position and why I was suddenly not suitable.
