How would you decide whether an AI agent is good enough to ship?

"A thorough, well-structured process: recruiter screen, hiring manager screen, a take-home case, a virtual onsite of four rounds (product sense, bar raiser/culture, technical execution, ML fundamentals), and a final conversation with a senior product leader. The interviewers were friendly, engaged and clearly hands-on practitioners. Each round probed a different angle, so you get to show range. The recruiting team was responsive and gave candid feedback mid-process, which I appreciated. What didn't go as well was logistics near the end. A late-stage round was cancelled at short notice and rerouted to a different interviewer, who treated it like an early screen, so I wasn't sure what was left. With interviewers across time zones, some slots also fell late in my evening. I didn't get an offer. Looking back, the gap was answer length and audience awareness in the senior rounds, not technical depth."
