What Microsoft Looks For
Growth Mindset
Satya Nadella transformed Microsoft's culture around growth mindset—the belief that abilities can be developed through dedication and hard work.
| Fixed Mindset | Growth Mindset |
|---|---|
| "I'm not good at this" | "I'm not good at this yet" |
| Avoids challenges | Embraces challenges |
| Ignores feedback | Learns from feedback |
| Threatened by others' success | Inspired by others' success |
Core Attributes
| Attribute | What They Assess |
|---|---|
| Collaboration | Do you make others better? |
| Customer Obsession | Do you think from the customer's perspective? |
| Diversity & Inclusion | Do you value different viewpoints? |
| Integrity | Do you do the right thing? |
| Continuous Learning | Are you always improving? |
Coding Interviews
Format: 2-3 rounds, 45-60 minutes each. Usually 1 problem per round, going deep.
Microsoft's Style
- Collaborative: Interviewers act as teammates, not adversaries
- Hint-friendly: They'll guide you if you're stuck
- Deep exploration: Expect follow-up questions on your solution
- Real problems: Questions often relate to actual Microsoft challenges
The Flow
1. Understand (3-5 min)
"Let me make sure I understand. We're looking for... Can I assume...?"
2. Discuss Approach (5-7 min)
"I see a few approaches. Let me walk through the trade-offs..."
3. Code (25-30 min) Write clean code. It's okay to ask clarifying questions mid-coding.
4. Test & Extend (10 min) Walk through examples. Handle follow-ups: "How would you modify this if...?"
High-Frequency Topics

|---|---|
| Arrays & Strings | Very High |
| Linked Lists | High |

The "As Appropriate" Round
This final interview with a senior leader is critical.
What they assess:
- Overall judgment and decision-making
- Long-term potential and trajectory
- Culture fit at a deeper level
- Red flags from other rounds
How to prepare:
- Be ready to discuss your career story cohesively
- Have thoughtful questions about the org and team

Note: Level 63 (Senior) is considered the "career level"—you can stay here indefinitely.
8-Week Prep Plan
| Weeks | Focus |
|---|---|
| 1-2 | Data structures review, easy-medium LeetCode |
| 3-4 | Medium-hard problems, Microsoft-tagged questions |
| 5-6 | System design fundamentals, cloud architecture patterns |
| 7 | Behavioral stories with growth mindset angle, mock interviews |
| 8 | Full mock loops, rest, final review |
Daily rhythm: 2 problems, practice explaining solutions, read one Microsoft engineering blog post.
Common Mistakes
- Arrogance — Growth mindset means humility. "I know everything" is a red flag.
- Not asking for help — It's collaborative. Asking clarifying questions is encouraged.
- Ignoring the AA round — This round matters. Prepare for it specifically.
- Generic behavioral answers — Show growth mindset explicitly.
- Not knowing Microsoft products — Use Teams, Azure, VS Code. Have opinions.
- Rushing through design — They want depth, not surface-level answers.

5 Things That Actually Matter
- Growth mindset is real — Weave it into every answer
- Collaboration wins — Make the interviewer feel like a teammate
- Customer obsession — Think from the user's perspective
- Depth over breadth — Go deep on problems, don't just skim
- The AA round matters — Prepare your narrative for leadership
