I recently attained the Microsoft hiring drive.
Online Assessment (HackerRank)
Two coding questions focused on data structures and algorithmic efficiency.
Result: Received feedback after week.
All subsequent rounds are in a single day.
Received the invite for R1 and R2. If these are positive, then R3 will be scheduled.
R1: Technical Loop (Coding & C++ Fundamentals)
Problem Solving: Implementation-heavy question based on LRU Cache. The problem was framed as a HackerRank-style story rather than a direct request.
Follow-up: Discussion on optimizing the cache and handling edge cases.
C++ Basics: Questions on C++ standards (STL, memory management, and modern C++ features).
R2: Technical Loop (Algorithms & C++ Standards)
Coding: Story-based problem involving Priority Queues (Heaps).
Implementation: Required a clean implementation with a focus on time and space complexity.
Cleared both R1 and R2 and got call from HR to R3.
R3: System Design (HLD/LLD)
Problem: Design an Alert Monitoring System.
Requirements:
The system monitors multiple machines, each equipped with various sensor types (e.g., Temperature, Pressure).
Each sensor has a defined lower and upper threshold.
If a value falls outside this range, an alert must be triggered and sent to the monitoring system.
User Interaction: Users must be able to view alerts and manually update the state of the alert (e.g., Acknowledged, Resolved, Ignored).Immediately get a call that clears the R3 from HR and schedule the Hiring Manager round on the same day.
R4: Hiring Manager (AA Round)
Project Deep-Dive: Detailed discussion on the architecture and impact of the current project.
Behavioral & Scenario-Based:
How do you handle critical customer issues and high-pressure escalations?
Conflict resolution within a team.
Coding: One foundational coding question to check quick problem-solving skills under pressure.
