Just finished Meta interviews. Coding wasn't crazy, but AI Coding + System Design are what really separate candidates.
Meta OA Process
Meta OA is more like an "entry ticket".
- 2 Algorithm Questions + 1 Small System/Logic Question.
- Medium difficulty. Focus on correctness and clarity.
Onsite Experience
Round 1: Behavioral (BQ)
Focus on explaining your thought process and decision-making, not just memorizing STAR templates.
Round 2: Coding (Medium+)
- Maximal Square (DP)
- Simple DFS/BFS Key: Clear logic, clean code, complete corner cases.
def maximal_square(matrix):
# DP solution implementation
pass
Round 3: System Design (Entry-level but Critical)
Standard architecture diagram. Key: Engineering mindset and scalability awareness. Interviewers ask "What if users 10x?" or "What if shard fails?".
Round 4: AI Coding (The Real Differentiator)
This round truly separates candidates.
- Language Constraint: Only Python supported in my case.
- Task: Tokenize, count frequencies, return top N.
- Follow-up: "What if text is huge?" -> Generators, chunk processing, parallelization.
Key: Quick understanding, implementation, and scalability.
Summary & Preparation
| Round | Rating |
|---|---|
| Intensity | Medium-High |
| Critical | AI Coding |
| Secondary | System Design |
| Baseline | Coding + BQ |
Meta values engineering mindset and adaptability over just grinding LeetCode.
