The follow-up questions were exactly what I got asked at Google. "What if the input was 10x larger?" Nailed it.
The system design questions were exactly what I got asked. "Design a rate limiter for an API with 100M requests/day." Word for word.
Anthropic's bar is insane. The AI follow-ups here—"What if this runs on a GPU cluster?"—prepared me for the depth they expect.
Used this for my Amazon loop. The DP questions were spot-on. Got the exact same problem in my onsite.
When you're interviewing for a company building AGI, you need to think at a different level. This got me there.
