THE ESSENTIALS

What to expect from a Microsoft internship interview

Microsoft assesses how you think, learn and collaborate—not only whether you memorised an answer. The exact format depends on the internship and team.

What Microsoft confirms

Its student interview guidance describes an initial interview and, for selected candidates, a final interview. Some roles involve coding, portfolios or work examples. University interviews are described as virtual.

What candidate reports suggest

Some software engineering interns report online assessments, coding interviews and behavioural questions. These reports vary by team and year; do not assume a fixed number of rounds.

Important: The questions below are original preparation exercises, except where a historical candidate report is specifically identified. They are not a leaked Microsoft question bank.

Microsoft internship interview process

A simple visual map based on Microsoft’s official student guidance, not a guaranteed sequence for every applicant.

01

Apply online

Choose a relevant internship and align your CV with the posted skills and projects.

02

Initial interview

Discuss your projects, foundational knowledge, motivation and role-specific skills.

03

Final interview

If selected, meet potential colleagues for further behavioural or functional evaluation.

Depending on role, a coding assessment or portfolio discussion may also be requested. Follow the details provided by your recruiter.

Choose your internship interview track

Different Microsoft teams need different evidence. Prepare the questions most relevant to the role you actually applied for.

31 Microsoft internship interview questions and answer guidance

Filter by internship discipline, then expand any question for a suggested answer structure. Use your own genuine experiences.

Candidate-reported example: implementing a queue using stacks appears in a 2026 Microsoft interview report on Glassdoor. Its inclusion here does not imply it will recur.

Worked coding interview: queue using two stacks

This classic data-structure problem tests explanation, correctness, complexity and edge-case testing.

Prompt

Implement a FIFO queue using two LIFO stacks. Support enqueue, dequeue and peek.

class QueueWithStacks:
    def __init__(self):
        self.in_stack = []
        self.out_stack = []

    def enqueue(self, value):
        self.in_stack.append(value)

    def _shift(self):
        if not self.out_stack:
            while self.in_stack:
                self.out_stack.append(self.in_stack.pop())

    def dequeue(self):
        self._shift()
        if not self.out_stack:
            raise IndexError("empty queue")
        return self.out_stack.pop()

    def peek(self):
        self._shift()
        if not self.out_stack:
            raise IndexError("empty queue")
        return self.out_stack[-1]

Complexity: Each element is moved at most once between stacks. Operations are amortised O(1), although one dequeue may take O(n). Storage is O(n).

Test cases

Enqueue 1, 2, 3; dequeue → 1; enqueue 4; dequeue → 2; peek → 3; then drain and test empty-queue behaviour.

What to say aloud

Clarify the contract, explain why the second stack reverses order, walk through a trace, then discuss amortised analysis and errors.

Visual: where coding interview effort goes

Clarify → Plan

Confirm inputs, outputs and constraints before typing.

Implement → Test

Write runnable code and cover boundaries and failure modes.

These are preparation steps, not official Microsoft scoring weights.

Worked product management case: improve Microsoft Teams for students

An original product interview simulation for interns. It is not a documented Microsoft interview question.

1

Define the user

University project teams coordinating classes, deadlines and shared documents.

2

Choose a problem

Meeting decisions get lost across chat, calls and files.

3

Propose and test

Summarise decisions into shared tasks, with user review and opt-in controls.

Hypothetical experiment: task completion

Illustrative numbers for interview maths, not real Teams product performance.

57%Control
69%Variant

Result: +12 percentage points, approximately +21.1% relative improvement (12 ÷ 57). Discuss sample size, statistical uncertainty, user trust and accessibility before launch.

Follow-up questions

How would you prevent incorrect AI-generated tasks? What if engagement rises but students feel overwhelmed? Which metric best captures useful collaboration rather than clicks?

Data and business internship practice cases

Data science: evaluate a classifier

Suppose a model flags 100 risky events, 80 are truly risky, and it misses 20 additional risky events. Precision = 80/100 = 80%; recall = 80/100 = 80%. Explain the costs of false positives and false negatives.

Finance: subscription revenue

Suppose 10,000 customers pay $20 monthly and churn is 2% monthly. Starting monthly recurring revenue is $200,000. Holding price and ignoring acquisition, next month is $196,000. Explain upsell, usage, contracts and churn assumptions.

Behavioural questions: show growth mindset with evidence

Microsoft recommends the STAR(R) structure: Situation, Task, Action, Result and Reflection. Include what you learned and how you would improve.

S + T

Set the scene

Give the context and your responsibility, briefly.

A + R

Show ownership

Explain your decisions and measurable outcome.

R

Reflect

Show feedback, humility and what changed next time.

Microsoft internship interview FAQs

What is the Microsoft internship interview process?

Microsoft says student applicants generally have an initial interview and, if selected, a final interview. The format and assessments depend on the internship role and team.

Are Microsoft internship interviews virtual?

Microsoft’s current university internship guidance states that interviews are conducted virtually. Follow your invitation for current logistics.

Do all Microsoft interns take a coding test?

No. Coding may be part of software engineering and other technical interviews, while business and creative roles can use different assessments.

How many rounds are there?

Microsoft describes an initial interview and a possible final interview for students. The number of individual conversations varies by role and team.

What coding topics should I prepare?

Review arrays, strings, hash maps, linked lists, trees, graphs, recursion, complexity, and how to test your solution.

Are these actual Microsoft interview questions?

Most questions here are original, role-relevant practice prompts. A queue-with-stacks question has appeared in a candidate-submitted interview report; such reports are not guaranteed future questions.

What should I ask my interviewer?

Ask about team challenges, internship project scope, mentorship, code review, success measures and how interns receive feedback.

How long should I prepare?

A focused 14-day schedule can provide structure, but adjust based on your baseline and the role.

Research sources and further preparation

Official Microsoft sources are prioritised. Third-party candidate accounts are labelled separately.
