AI interviews · Engineers — the AI round, debugging, design and open builds

Design rounds, open-ended builds and the long build

Not every AI round hands you a repo and three phases. Some give you an empty repository and keep adding requirements; some give you hours to build a product with any tool and then make you defend it; and Meta now runs design interviews with the assistant in the editor. This lesson covers all three and the habit they share — the structure is yours, the typing is the tool's.
