Technical rounds fail for two different reasons — not knowing the material, or knowing it but not communicating it the way the interviewer is scoring for. These guides are split by what's actually being tested: coding rounds where the interviewer wants your thought process out loud, system design rounds where breadth of trade-off discussion often matters more than landing on "the right" architecture, and role-specific rounds (data, product, finance-tech) where domain vocabulary signals experience faster than a correct answer does.
