Tell me about a time you conducted a failed experiment.

"The process was recruiter screen, a 30-minute hiring manager call, a take-home on designing a free trial for ChatGPT Team, and then a four-round onsite. The unusual part was that they gave me the onsite behavioral questions ahead of time, which made me think the loop would be easier, but in reality the whole thing was extremely rigorous because almost all of the real evaluation happened in the follow-ups. I felt like every interviewer had very low tolerance for hand-wavy answers and wanted to see exactly how I thought, how I got alignment, and whether I had owned meaningful business outcomes end to end. I did not get the offer, and my big takeaway was that the literal job description matched my background pretty well, but the bar felt closer to a senior leader or GM-style operator willing to work as an IC."
