: Separating read-heavy data from write-heavy data. 3. Detailed Component Design (Next 15-20 Minutes) A system design interview is effectively a simulation
Furthermore, the interview is a test of communication. A system design interview is effectively a simulation of a work meeting. The interviewer is looking for a collaborator, not just a technical dictionary. The ability to explain complex concepts simply, to listen to hints from the interviewer, and to pivot when a design flaw is pointed out are soft skills that are often overlooked in text-based study guides.
