I interviewed with someone from a recruiting firm on behalf of the company, they didn't call me back for a second interview and although I was promised an answer within one week it took them 2 months to send me an email telling me that I won't get a second interview. Also the interviewer had no idea about the company, she told me to ask any questions that I have then repeatedly said she doesn't know much.

It was in person, on campus and it was an okay interview. I didn't take the time to prep but you definitely need to know some things going in. Definitely have a professional attitude during the interview nothing less. Make sure you know a lot about the position and why you want it.
