I was first contacted by a recruiter for a phone screening. She was very nice and informative. At the end of the interview she told me what I should expect and learn about before my next interview with someone on the team. I got asked basic HR questions like "Why Facebook?" "Why this job?" and one specific ? "How can you benefit from fraudulent facebook credits?" (didn't have a great answer, but she explained it afterwards) Thought it went great.
My next interview didn't go as well. Which wasn't really the interviewer's fault, I just got really nervous and didn't really know what to expect as this was my first real interview, ever. I'd spent so much time learning everything I could about the company, the industry and the work I hadn't thought about questions she might ask about myself, which was what most of the interview was. She asked me why I hadn't pursued something closer to my major. She asked about a time I'd had a disagreement on a team and how I'd handled it. She asked only one question specific to the work at the very end, asking me to get in the mind of a fraudster. Don't get too chatty, because it seemed a little awkward when I tried. And have prepared, general questions for the end if you are totally new/knowledgeable about the work. The questions I asked about her work she seemed confused by.
