Interviewers at companies like Google, Meta, and Netflix are trained to spot memorized answers. If you copy a architecture blueprint from a PDF without understanding why those choices were made, the interviewer will pivot the conversation to expose the gaps in your knowledge.
Interviewers do not look for a single "correct" architecture. Instead, they evaluate your signal across several core competencies:
