eBay interview questions

The position was Traffic PM and involved driving traffic to ebay's website from various channels. I got a call from the recruiter to schedule the interview. I was expecting a behavioral interview but the interviewer went into every detail in my resume. He asked about a small business I had built, and played the devil's advocate. He challenged my strategies and asked me how I would react if a competitor tries to explore my space. He also asked me questions like how we can improve ebay. I talked about improving search, and gave him a suggestion. He asked me how I would implement it. I think I did well but didn't receive an offer. I asked for my interviewer's feedback, which was really helpful. It was a great experience. The overall process was pretty fast; I interviewed on a Friday, and was told the result on the next Monday.
