Anyway, I'll attest to the fact that Dan at least didn't veto all candidates purely on the basis of their response to this question (unless I was the result of a massive clerical error).
Outcomes aside, I'm very thankful for my experience at Optimizely. My time there was a major inflection point for me both personally and professionally. I wouldn't be as effective in the workplace as I am today—nor would I have some of my most meaningful friendships—had I not cut my teeth at 631 Howard — thanks Dan (and Pete, if you're reading this too).
EDIT: Also considering the timeline and the role described in the OP's message, there's a nonzero chance we were interviewing for the same role. Small world!
