If Spotify were integrating Sierra for its customer support chatbot, what would that technical system look like?

"I got pulled into the process pretty quickly after a recruiter conversation, and they moved me forward without a lot of setup. The loop was recruiter, then an unusually early technical filter round on designing an agentic AI support system, then a take-home prioritization case, then three final-style interviews: case presentation plus a live metrics case, a stakeholder-management round that was really product sense, and a fit deep dive. The whole thing felt very practical and very tied to the real job of helping big customers get Sierra working, which I liked. At the same time, it felt half-hazardly put together because a lot of interviewers seemed new to the process, made mistakes in the case flow, and I basically had no reliable prep material going in."
