Microsoft Interview Trend Analysis (2026 Q2)

Overall Trend

Over the past 3 months Microsoft interviews split clearly into four distinct tracks: traditional SDE / MAI (Microsoft AI) / Applied Science / Hiring Event (HE). Traditional SDE orgs (Azure, Teams, Windows, Excel, Core OS) stay LC Easy–Medium, with Cache-class questions (LRU / LFU) and Rate Limiter as near-mandatory staples. Hiring Event uses a fixed 4-round × 1-hour format, heavy on BQ + Coding, written on HackerRank with standard I/O and often lightly disguised LC variants. MAI is the track that has shifted the most — classic LeetCode is largely gone, replaced by beam-search / sampling, stop-token streaming detection, resumable dataloader, SFT sample packing, KV store with snapshot, in-memory DB — i.e. "mini ML / infra coding exercises", many of them lifted directly from the OpenAI interview bank. Applied Science is the most standardized: ML trivia + hand-written k-means + project deep dive + one case study. Recruiter / HR coordination has become noticeably chaotic — no context from HR, interviewers arriving late or ending early, VOs getting canceled, no feedback afterwards are all common. [hidden].

Difficulty Trend

Overall Medium, but the MAI track noticeably pushes the "odd question" rate up — many coding prompts come straight from the OpenAI bank or from internal workloads, and under-preparation leads to immediate wipeouts.
