First interview consisted of a video interview, where I basically recorded my answers to questions via a app. There were 8 questions, 3 minutes to answer each, 30 seconds to prep for each question. A little thrown off, as I was expecting the interview to be mostly behavioral-based, with maybe 1 case question. There ended up being 4 case questions if I remember correctly. The 2nd interview was with the hiring manager and it was over the phone. It lasted around 45 minutes and contained both behavioral and case questions. Make sure you study hard on their various promotions, as questions were heavily geared towards that (i.e. "if we are discounting x product by 20%, how would you promote this promotion to customers?"). Sign up for emails before interview and study the promos they send you. Also, make sure you have a very good understanding of the site and its functionality. The interviewer was extremely nice and personable. He laughed when I said funny things and answered my questions very well. I thought I had done well on the phone interviewer, but was not invited onsite. I believe this has a lot to do with my lack of experience, even though the interview itself was good.
