About the Tencent Software Engineer hiring loop

Tencent hires across business groups (WXG / IEG / CSIG / TEG) with distinct rubrics each. Internal tier ladder is T1.1–T5. Interviews routinely switch between Mandarin and English. Game-systems design is unique to IEG.

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.
