Yonder .NET Developer interview questions

I had a discussion with an HR in order to get to know each other. It wasn't a technical interview. At the end of the meeting, she told me that i would receive a feedback in 2 days (if we will go further to a technical interview or not). 2 weeks passed, no feedback, so i sent her an email where i asked nicely for the feedback. Still, no response. Totally unprofessional!
