Meta's engineering culture centers on values:
Move Fast. Ship quickly, iterate, break things (responsibly). Speed of execution matters more than perfection.
Be Bold. Take on hard problems. Propose ideas even if they might fail.
Build Social Value. Think about user impact. How does your work affect the + billion people using Meta products?
Focus on Long-Term Impact. Don't just fix symptoms. Build systems that last.
Be Open. Share information freely. Give and receive feedback directly.
