Microsoft's external careers run at jobs.careers.microsoft.com, which redirects to apply.careers.microsoft.com. The candidate-facing layer is Eightfold AI, an AI talent-intelligence platform. There is no Workday, Taleo, iCIMS, Greenhouse, or Lever in the path to a Microsoft role.
How we know: Microsoft's own Responsible AI transparency page states it has assessed its implementation of Eightfold for talent acquisition, and the live apply flow loads Eightfold's platform.
What Eightfold does: it reads your resume, builds a skills profile, and matches you to roles using AI, and can surface you for roles beyond the one you applied to. So role-relevant skills named explicitly, each tied to a result, matter more than keyword density. Keyword-stuffing still backfires once a human reads it.
The sufficient condition is content that proves impact: quantified scope mapped to Microsoft's four hiring values below. Clean formatting gets you parsed; measurable outcomes get you advanced.
