EFC Systems interview questions

I was given a phone screen assessing my technical skills, then a take home assignment that takes bout 5-8 hours. After I submitted it, I was brought on-site for a panel interview.

I received an email from one of the recruiters who had received my resume and we set up a phone screening. During the phone call, we talked about my experience and he decided to invite me up to do an in person interview. When I got to the interview, it turns out they really don't even use one of the programming languages the person over the phone told me that they did and one of the interviewers was extremely rude to me. He kept being very condescending toward me. I am a recent college graduate, so of course, I really haven't saved the world yet.
