OpenAI’s current interview guide describes a team-dependent process, explicit tool rules, and the published engineering focus without implying one universal loop.

Preparation use of AI never establishes permission during an assessment.
Official guidance, approved candidate reports, Engineering Foundry recommendations, and private recruiter-confirmed details remain separate. A report never becomes company policy.

These are qualitative Engineering Foundry recommendations, not claimed interview weights or predicted questions.
Engineering Foundry recommendationcore
Coding / DSA
Practice data structures, algorithms, complexity, testing, and explanation without treating company tags as predicted questions.
Practice responsibilities, interfaces, state, failure handling, and testability only when the role or recruiter context makes object design relevant.
Engineering Foundry recommendationrole dependent
System Design
Practice requirements, capacity, data, reliability, trade-offs, and evolution when the role calls for architecture depth.

ML System Design
Use ML Design only for ML, data, model, or infrastructure scope supported by the active role.
Engineering Foundry recommendationcore
Behavioral / values
Build truthful examples around decisions, collaboration, impact, feedback, and learning. Do not infer a hidden company rubric.
Level expectations
Engineering Foundry uses Entry, Mid, Senior, and Staff+ as preparation bands. The active job posting and recruiter-confirmed scope are authoritative for this application.
