Netflix, Airbnb, Uber, Lyft, Meta, etc.
What they test:
- System design at scale (petabytes, millions of events/second)
- Strong coding fundamentals (Python, SQL optimization)
- Data modeling for complex domains
- Trade-off discussions (consistency vs availability)
Interview loop:
- - coding rounds
- - system design rounds
- behavioral round
- Often a take-home or SQL assessment
Preparation focus:
Scale thinking. "What happens when data grows x?" Practice designing data platforms, real-time systems, ML pipelines.
