As a product manager for Meta, design a product for volunteers.

"I interviewed in late January for an L5 PM role on Meta's AI track, and the recruiter straight up told me the process had changed the week before. I first did a traditional product sense screen and a traditional analytical screen, then there was a pause while they reviewed those before deciding whether to give me an intermediate AI product sense round. That AI round was the unusual part: about 30 minutes of normal product sense and then a switch into Meta's Llama tool to vibe code a prototype live. It felt like I was one of the early guinea pigs because even the interviewer seemed to be figuring out the format in real time. I got tripped up by technical follow-ups on latency, token usage, retrieval, and compute, and I didn't make it to the final loop."
