Microsoft Interview Question Bank

Microsoft runs two parallel hiring tracks: the standardized Hiring Event (HE) loop covering Azure, Cloud, Copilot, and Office orgs, and Mustafa Suleyman's MAI org with its own recruiter pool and a distinctly OpenAI-flavored coding rotation. The HE bar is consistent — four 60-minute rounds back-to-back on a fixed weekday — with medium-difficulty algorithms and one system-design slot; MAI loops add project deep-dive depth and pull problems from an in-memory-DB / beam-search / streaming-decoder pool that does not overlap with classic LeetCode prep.
