Beyond, Inc. interview questions

Recruiter convinced me to interview despite my better judgement. Overstock has a bad rep locally as a bit of a sweat shop and one that tends to lay people off regularly. My recruiter said things had changed in the past few years. I arrived around 11am and met with 2 senior level guys. They had me write code for a binary tree traversal on the board and asked a series of questions. After that, 2 different guys took me to lunch. Lunch seemed geared around getting to know me as a person and didn't involve and traditional interview questions. It was very casual. After lunch, I got a small tour of the building and met with 3 other guy who grilled me technically for a while. Lastly, I met with a higher up (VP type) and was given the Overstock sales pitch. Overall, I thought the interview was fairly easy despite being a 4 hour ordeal.

I initially received a call from the hiring manager to schedule a phone interview and interviewed with the manager a few days later. The call lasted about 40 minutes and covered my work experience and how that related to the specific job that I was applying for. One question that I was asked was what metrics I would use to assess the effectiveness of a particular channel. Overall I would say that the interview was very cordial and professional and I enjoyed the interview process.
