I got an email tell me to call someone in HR. We chatted, when over simple questions like my previous experience, how I found out about the internship. She asked what I was interested in. I mistakenly downplayed one of my major skills which directly related to the area I wanted to intern in, which might be why she told me it was already filled. I was offered two different areas and after I chose one, she asked me questions related to the department. This was much easier than I had assumed.
