Chemonics International Writer/Editor interview questions

I was contacted one week after submitting my application for a phone interview with an HR representative. During the interview, the HR person spoke a bit about the company and the job, then asked me to speak on my background. She asked me to take her through my resume, then asked a few job-specific questions. She said that she would get back to me either way within three weeks, but she never did. She did not even respond to my follow-up email. I thought this was pretty rude and unprofessional, obviously.
