Microsoft Interview Questions

Microsoft's bank runs to 266 questions and is coding-first by a wide margin. Coding & Algorithms holds 108 of them, more than triple System Design at 33, with Behavioral & Leadership at 22, Machine Learning at 20, ML System Design at 14, and engineering fundamentals at 13. Software Engineer is the dominant role at 144, followed by Data Scientist at 44 and Machine Learning Engineer at 33. Technical screens carry 107 questions and onsites 99, with 15 from online assessments and 11 from HR screens. Ratings are 171 medium, 41 hard, and 20 easy, and 34 are tagged Senior+. The algorithm prompts skew graph and grid: minimising fuel cost across cities, minimum moves on a grid with k-cell jumps, lowest common ancestor in both a binary tree and a binary search tree, merging overlapping intervals, and maximising a product after a shared XOR. Concurrency turns up too, in a bounded per-key ordered task executor. Data Scientist rounds move to judgement calls, building and defending a baseline model from a CSV, analysing an AI product pilot to decide whether to expand it, and evaluating a product change that adds more user options, while ML System Design covers a retrieval-grounded local sports news recommender. 17 questions were added in the last 90 days, 1 round is tagged AI-assisted, and 30 first-hand interview experiences are on the site.
