Filled out application, received a phone call to plan interview, had phone interview a week later. Overall, I didn't feel very good about my interview, but I believe that others have felt this way in the past and still got the job. I got the impression that the interviewer was challenging me or expecting me to answer a question "wrong."

Short, quick, personable and exciting so you can't gauge how they feel. That said, very easy and fast process, does not require much preparation, just make sure you can pitch yourself well.
