The phone interview seemed very casual, I got asked about my experience. It definitely felt like I had to be the guide through the interview. They take about a week in a half before giving you an response about the second interview. Very nice interviewer but not the one that decides. The first interview is more of a filter. I don't think it was difficult, but I do think that you should have a prepared outline of how you want to highlight whats on your resume and also what wasn't said on your resume.
