Microsoft Interview Experience (Feb 2026 | 4 Rounds)

I applied for multiple roles. The recruiter reached out on 23 Feb and scheduled the first 2 rounds on 27 Feb.

🔹 Round 1 – LLD (Multi-Level Parking Lot)

• 5 min intro
• 10 min discussion on my first project mentioned in my resume
• LLD: Design Multi-Level Parking Lot

The expectation was a basic working implementation, not over-engineered.

I implemented:

• Vehicle (Car etc.)
• Ticket
• Floor
• Slot (CarSlot etc.)

I faced minor debugging issues; the interviewer was patient and even gave an extra 10 mins. I completed it successfully.

🔹 Round 2 – DSA

• 5 min intro
• 5 min project discussion
• 35–40 min DSA Problem:
  https://leetcode.com/problems/meeting-rooms-ii/

I initially chose a suboptimal approach. After implementing and testing, I realized it fails for complex cases.

I was asked to switch to the optimal approach discussed earlier — the interviewer agreed calmly.

I reimplemented it in ~5 mins. All test cases passed.

🔹 Round 3 – LLD (Snake & Food)

• Short intro
• 10–15 min project discussion
• LLD: Design Snake & Food

This time, I didn't have to run the code.

I used:

• Strategy pattern
• Factory pattern
• Extensible design

I answered optimization questions and updated the design. The interviewer seemed satisfied.

🔹 Round 4 – Senior Manager (Behavioral + System Design)

Focus: Team fit, depth, maturity.

Questions:

• 10 min, Recent project deep dive (very detailed)
• 5 min, Non-technical feedback I received
• System Design: Design Notification Service

Environment

DSA/LLD: Java | Hackerrank | Single Solution.java (must run)
Design: draw.io withing hackerrank

Currently waiting for verdict 🤞
