About the Microsoft Software Engineer hiring loop

Microsoft uses the SE → Senior SE → Principal → Partner ladder. System design assumes Azure-native primitives (Cosmos DB, Service Fabric, AKS, Front Door). Behavioural rounds reward Growth Mindset framing over STAR. Questions indexed by org (Azure, M365, Xbox, GitHub, LinkedIn, Bing).

Coding rounds are scored on correctness, clarity, complexity statement, edge-case enumeration, and testability. System design is scored on scale anchoring, API definition quality, data-model trade-offs, and failure-mode reasoning.
