Meta: the loop, round by round

In Java interviews you write the code and the compiler is the only thing that talks back. At Meta one coding round hands you a multi-file codebase and an AI assistant, and the thing being graded is whether you notice when the assistant is wrong.

The notable format. Coding round 2 (AI-enabled) (★): Rolled out from October 2025. You get a multi-file codebase and an AI assistant, then extend it. Three phases: decompose a vague requirement into technical decisions, delegate implementation while keeping ownership of the architecture, and defend every line — including the ones the AI wrote. The most common mistake is accepting the AI's first output without validation. Source: Wrok (published 2026-06-15).

What this page can't tell you

This source describes the E5 SWE loop. It carries no Meta AI-engineer-specific loop; ask your recruiter whether your role adds a round.

Ask your recruiter

Will my loop include the AI-enabled coding round, and which assistant does it use?
Is my design round ML-flavoured or general?
