AAMC Software Engineer interview questions

Applied online and got a call from HR to set up phone interview. Phone interview was one-on-one and involved talking about past experience and not very technical. A week later, the onsite interview was scheduled and a couple of friendly developers did a purely technical interview (simple to medium complexity) followed by an interview by the project/hiring manager. I had a fairly good feeling after the interview, and I was told I will hear from them after a week, but they did not call, email, or communicate in any way. They did not have the common courtesy to let me know their decision. I probably did not get the job because there was a better candidate for the job. But what disappointed me was that they did not have the common decency to let me know.
