General Dynamics Information Technology interview questions

The hiring manager was quick to schedule the interview. The interview was rather basic, but went well. I was told I was a top candidate for the position and I would hear something by the end of the week. Unfortunately, I never received a callback for the position with positive or negative feedback. I sent a follow up email and still did not receive a reply. I am not upset that I didn't get the position, but that the hiring manager stopped all contact. I simple "we found someone better suited for the position" would have been perfectly fine. In my opinion this was very unprofessional.
