Enova Strategy and Operations interview questions

I dropped off my resume at their booth during Career Fair at my university. I received a call same evening, for an interview on campus the next day. I was told it would be a 30 min interview which would include case questions and behavioral questions. During the interview, the interviewer started off with asking questions about my resume, why I wanted to work at Enova. Then he moved on to the case. It was a case question based on probability. Fairly easy, however every answer I gave, I was cross-questioned. After the case, he asked me if I had any questions about the Internship or the Company as a whole. Lasted about 40 minutes in total.
