Dexter Systems (Virginia) Java and Net Developer interview questions

I applied through university job board and the process took only a few days. Received an email to answer certain questions which I did. After that, I received a call at the same day from a man which a thick Indian accent. The man became rude when I asked him to repeat the question because I could not clearly understand him. However, when he learned that I do not have JAVA or .Net experience he said that they were looking for candidates with those experiences and ended the phone conversion with an abrupt "bye" which is rude and foremost unprofessional.
