What the sources establish

Microsoft publishes official technical-interview guidance listing evaluated areas (problem solving, design, coding, testing) and role-dependent topics (algorithms, data structures, distributed systems, AI/ML, data science, networking), and a general hiring page stating that most interviews include 2 to 4 conversations of up to an hour and that candidates should demonstrate their own skills without outside assistance in assessments and interviews unless explicitly permitted. Both pages are undated. Not established: team-specific loops, screening formats, the exact interview count for a given role, and new-graduate or intern specifics, which are on a separate page not read here.

   Official

   Microsoft Careers. Undated page; read 2026-10-05. Read in full for this page.

   Scope: Technical roles generally; the page says the areas to prepare depend on the role

   Documented by this source

   • Technical interviews assess problem solving and the skills for the role, plus questions about past experience and how you would approach role-related scenarios
   • Problem solving: break the problem down, ask clarifying questions, plan before implementing, and manage time within what the page calls a short 45-minute interview round
   • Design: understanding what it takes to build or design a new system or platform, not only to work within an existing one
   • Coding: clean, concise, bug-free code in the language you are strong in, without pseudocode, in a third-party tool where you can run and compile your code
   • Testing: test your solution before calling it done, considering security implications, stress, boundaries, error conditions and corner cases
   • Algorithms: recursion, the details of at least one (preferably two) O(n log n) sorting algorithms such as quicksort and merge sort, and Big-O analysis
   • Data structures: arrays and strings, queues and lists, linked lists, trees and tries, hash maps and sets, and graphs, including when to use each
   • Role-dependent areas: system design and distributed systems (SOA, n-tier architecture, resiliency, high availability, auto-scaling, replication, CAP, partitioning), AI/ML, data science (data manipulation, probability, statistics) and computer networking (layering, HTTP, TLS, TCP/IP, BGP, IS-IS)

   Outside or AI tools, according to this source: Does not address AI tools. It states that coding happens in a third-party tool where you can run and compile your code. Follow the instructions in your own assessment invitation.

   • Undated; the role-dependent topic list is described as representative, not exhaustive.
   • Does not give the number of interviews or a screening format.

2. How we hire (Microsoft Careers hiring tips)

   Official

   Microsoft Careers. Undated page; read 2026-10-05. Read in full for this page.

   Scope: All Microsoft roles; describes the recruiting lifecycle and the candidate code of conduct

   Documented by this source

   • Structured interviews with a consistent framework; Microsoft says it looks for respect, integrity, accountability and a growth mindset
   • Hiring teams may start with a brief screening conversation; most interviews include 2 to 4 conversations with potential teammates and cross-functional colleagues, each lasting up to an hour, by phone, on Microsoft Teams or in person
   • Candidates should show how they meet the qualifications through specific past examples, ideas for approaching the role, and transferable skills; some roles ask candidates to write code or provide work samples
   • Candidate code of conduct: honest representation at every stage, and responsible AI use as described in the tool policy

   Outside or AI tools, according to this source: Encourages responsible AI use for preparation; during assessments and interviews, candidates should demonstrate their own skills without outside assistance unless explicitly permitted. Follow the instructions in your own assessment invitation.

   • General to all roles; the interview count is a typical range, not a fixed rule.

Our preparation recommendation

Our recommendation, not Microsoft guidance: prepare runnable, tested solutions, since the technical page says you code in a tool that compiles and runs code and expects you to test before saying you are done. Cover the algorithms and data structures it names, including recursion and the O(n log n) sorts, and prepare system design if your role involves services. Add AI/ML, data science or networking only when the job posting or recruiter points to them, because the page presents those areas as role-dependent.

1. Complexity analysisNot started

   The page expects you to explain the Big-O complexity of your algorithm.

2. Sorting and binary searchNot started

   Knowing at least one, preferably two, O(n log n) sorts in detail is stated explicitly.

3. Recursion and backtrackingNot started

   The page names recursion as a common pattern for some questions.

4. Linked listsNot started

   Linked lists are in the page’s data-structure list.

5. Trees and binary search treesNot started

   Trees and tries are in the page’s data-structure list.

6. Graph traversal: BFS, DFS and componentsNot started

   Graphs are in the page’s data-structure list.

7. Correctness, invariants, edge cases and testingNot started

   Testing your own solution, including boundaries, error conditions and corner cases, is a stated expectation.

8. System design methodNot started

   Design is an evaluated area, and system design questions draw on distributed-systems knowledge.

9. Replication, quorums and consensus (Raft)Not started

   Replication, partitioning, CAP and high availability are named for system design questions.

10. Behavioral stories and values-based questionsNot started

    Interviews also ask about past experience and role scenarios; prepare specific examples.

Confirm with your recruiter

• How many interviews your loop has, their length (the pages mention conversations of up to an hour and a 45-minute round), and which areas each covers.
• The level and team, and whether system design, AI/ML, data science or networking topics apply.
• Which language you will code in and which coding tool is used (the page says it can run and compile code).
• Whether any AI assistance is explicitly permitted for a given assessment; without such permission, the candidate code of conduct says to work without outside assistance.
• Whether there is an online assessment, coding exercise or work sample before the interviews, and its rules.
• Logistics: phone, Microsoft Teams or in person, and accessibility accommodations.

Limitations of this page

• Both pages are general across technical roles; team-specific loops are not described.
• Student and recent-graduate interview guidance exists on a separate Microsoft page that was not read for this entry.
