FAQ

Does Netflix have a coding round?

Yes. In the Netflix loop this shows up as "Coding": Practical problems; less puzzle-y, more real-world.

How many problems should I practice?

Quality over quantity — deeply understanding ~150 problems across the core patterns beats grinding 500 shallowly. The goal is to recognize the pattern, not recall the exact problem.

Should I talk while coding?

Yes. Interviewers score communication. Narrate your approach, tradeoffs, and edge cases as you go — silent correct code scores worse than communicated correct code.
