Here’s a list of the questions I was asked during my Meta interview process: Recruiter Screening 1. “Why are you interested in joining Meta?” 2. “Can you walk me through your background and how your experience aligns with this role?” 3. “What are your long-term career goals, and how does this position fit into those?” Coding Interviews 1. “Write a function to find the intersection of two arrays.” 2. “How would you implement a binary search algorithm? Can you walk through its time complexity?” 3. “Given a string, write a function to check if it is a permutation of a palindrome.” 4. “You have an n x n matrix. Rotate it 90 degrees clockwise in place.” System Design Interview 1. “Design a scalable system for storing and retrieving user profile pictures.” 2. “How would you approach designing a news feed system? Think about scalability and data consistency.” 3. “If you were building a messaging app, how would you ensure messages are delivered in the correct order?” 4. “Can you walk through how you’d design a distributed caching system?” Behavioral Interviews 1. “Tell me about a time you had to resolve a conflict within a team. What did you do?” 2. “Describe a situation where you had to work with cross-functional teams. How did you ensure alignment?” 3. “Have you ever faced a project where the requirements changed mid-way? How did you handle it?” 4. “What’s an example of a risk you’ve taken in your career, and what was the outcome?” Onsite Interviews 1. “Can you optimize the following code for time complexity?” 2. “Describe a time when you faced a technical challenge you couldn’t solve immediately. How did you approach it?” 3. “How would you handle designing a feature if you received conflicting feedback from stakeholders?” Each stage felt targeted and focused, testing both my technical skills and how I approach problem-solving and collaboration.
