I quit my 6-figure SRE job at Bank of America 2 weeks ago to build AI engineering interview prep. Here's where things stand. THE PROBLEM I KEPT SEEING Every engineer I knew preparing for AI roles at Anthropic and OpenAI was failing their technical rounds. Not because they weren't good enough, but because nothing prepared them for what these companies actually ask. AI engineering interviews in 2026 test RAG pipeline architecture, token efficiency, agent orchestration, and prompt injection defence. LeetCode covers none of this. Nobody was built specifically for AI engineering. So I quit and built it. WHAT I BUILT Velocode (velocode.ai) — interview prep for AI engineering roles. Three independent AI agents score every submission simultaneously on token efficiency, architecture, security, and correctness. Then Claude and GPT-4o both attempt the same problem, cross-score each other, and we synthesise the golden answer from both. No single model produces this alone.…
