Meta's Production Engineering (PE) role combines SRE with systems programming.
What to expect:
- Coding: Systems-level (C++, Python), practical problems
- Systems: Deep Linux knowledge, debugging at scale
- Design: Focus on Facebook-scale problems
- Behavioral: Collaboration with engineering teams
Preparation tips:
- Practice systems coding (file processing, network programming)
- Understand Linux internals (syscalls, memory management)
- Think at massive scale ( billion users)
Difference from Google: More coding-heavy, less theoretical. Practical problem-solving over book knowledge.
