This entry concerns a **Microsoft Software Development Engineer II** role at **Mid Level / L4**. It is marked **Verified**, concerns the **United States**, and was submitted **6 months ago**. The interview date is listed as **7 months ago**; the reported timespan is **1 month**, and the difficulty is **Moderate**. Our Microsoft Software Engineer Interview Guide was updated **a month ago by Microsoft candidates** and includes [an expert guide](https://www.aced.io/guides/microsoft-software-engineer-interview), [25 interview experiences](https://www.aced.io/guides/microsoft-software-engineer-interview/experiences), [102 questions](https://www.aced.io/guides/microsoft-software-engineer-interview/questions), and [138 resumes](https://www.aced.io/guides/microsoft-software-engineer-interview/resumes). ![Microsoft logo](https://exponent-static.s3.amazonaws.com/company_logos/microsoft.png) ## Candidate summary > In my binary tree round, I was not even leaning on BFS or DFS terminology, and they still liked my solution because I kept reasoning it out. That was the moment where Microsoft felt more about logical thinking than memorized interview patterns. ## Interview process The candidate describes a relatively long Microsoft SDE II process: 1. **Online assessment:** a HackerRank assessment. 2. **Recruiter screen:** a one-hour screen focused heavily on motivation and culture fit. 3. **Technical loop:** three back-to-back interviews covering coding, system design, and low-level design. Several prompts were vague, so the candidate had to ask questions to uncover requirements rather than immediately apply a textbook answer. In the coding round, interviewers appeared to value reasoning through a binary-tree problem more than using exact BFS or DFS terminology. The candidate rated the overall difficulty about the same as Google or Amazon, with somewhat more emphasis on logical thinking and culture. ## Interview rounds The experience contains **7 questions across 5 rounds**. The page exposes the online assessment and recruiter screen in the public preview; additional content requires membership. ### Online assessment — 2 questions The HackerRank assessment felt “black-box.” It contained two coding problems, but the candidate could not see the real test cases and had to infer requirements from examples. **Question types:** [Coding](https://www.aced.io/questions?type=coding) and [Data Structures & Algorithms](https://www.aced.io/questions?type=algorithms). #### 1. Convert an integer to a string of bytes [Implement a method to convert an integer to a string of bytes without using built-in helper functions.](https://www.aced.io/questions/6323) The candidate had to write the conversion logic without language helper functions. Hidden constraints and test cases made the behavior difficult to infer. The candidate interpreted the examples as implying **little-endian** byte order, although the prompt did not state that explicitly. #### 2. Connected components using union-set and graph traversal Solve a graph problem involving connected components using a union-set-style approach and graph traversal. The candidate recalls an edge-list-based connected-components problem and considered union-set together with BFS or DFS. The exact prompt and expected return format were not remembered; the candidate recalls that returning some form of connected-component list was central. ### Recruiter screen — 2 questions The rendered interview record describes a **45-minute** conversation with a senior interviewer. It was mostly open-ended, included a short follow-up near the end, and involved substantial pushback on tradeoffs. - **Question:** How would you improve a product you use every day for a new market? - **Candidate approach:** Choose a segment first, size it, compare three options, then select one option and define its success metric. The same question and response appear twice in the rendered record. ### Technical interview (1) The rendered record repeats the same **45-minute** senior-interviewer format, with open-ended questions, a short follow-up, and pushback on tradeoffs. - **Question:** How would you improve a product you use every day for a new market? - **Candidate approach:** Choose a segment first, size it, compare three options, then select one option and define its success metric. ### Technical interview (2) The rendered record repeats the same details: - **Format:** 45 minutes with a senior interviewer. - **Style:** Mostly open-ended questions, a short follow-up near the end, and pushback on tradeoffs. - **Question:** How would you improve a product you use every day for a new market? - **Candidate approach:** Choose a segment first, size it, compare three options, then select one option and define its success metric. ### Technical interview (3) The rendered record repeats the same details: - **Format:** 45 minutes with a senior interviewer. - **Style:** Mostly open-ended questions, a short follow-up near the end, and pushback on tradeoffs. - **Question:** How would you improve a product you use every day for a new market? - **Candidate approach:** Choose a segment first, size it, compare three options, then select one option and define its success metric. ## Interview tips The candidate recommends practicing aloud with a timer, keeping a framework ready for every round, and asking the recruiter what each interviewer focuses on so examples can be tailored accordingly. ## Company culture The candidate describes interviewers as collaborative and focused on the user. The team appeared to value structured thinking over polish, and interviewers left time for questions at the end. ## Unlock the full experience Membership provides the rest of this interview and new experiences added weekly.

He was like, \"let's code it out,\" and wanted me to build a file system with four use cases in 45 minutes, and then the recruiter just ghosted me for a month.” [Read the full interview](https://www.aced.io/experiences/microsoft-software-engineer-interview-89b7e7?returnPath=%2Fguides%2Fmicrosoft-software-engineer-interview%2Fexperiences) - **Software Engineer, Microsoft · Aug 2026 — 1 round, 1 question.** “still in progress but just leetcode prep. Studied some dsa and system design. Also dynamic programming helps.” - **Software Engineer, Microsoft · Jun 2026 — 1 round, 1 question.** “The round was easy - I had to go over my current responsibilities and my work. I was asked a coding question as well so prepare DSA well” [See all 25 Microsoft Software Engineer interview experiences →](https://www.aced.io/guides/microsoft-software-engineer-interview/experiences) ## Related Aced resources We provide preparation resources including courses for Product Management, Forward Deployed Engineering, Engineering Management, Software Engineering, System Design, Data Science, Machine Learning, Data Engineering, AI Engineering, Investment Banking, Generative AI, Security Engineering, TPM, Solutions Architect, UX / Product Design, and BizOps & Strategy.
