eBay interview questions

I submit my job applications by directly emailing one of their lead data scientists. She called me and asked a few questions about my research and background. Then she asked a very easy probability question related to gambling machine. Later she sent me a link to a dataset and asked me to analyze the data and return the code and results within two weeks

5 consecutive interviews for 5 hours. Two pertaining to past experience and previous projects, two technical interviews on statistical and SQL knowledge, and one personal interview. A lot of information pertaining to A/B Testing and previous experience is a must.
