Invent & SimplifyMedium~8 min
Simplified an over-complicated system
Interviewer: Tell me about a time you replaced something complex with something dramatically simpler. What did you cut, and how did you justify it?
Asked atAmazon· SDE2Amazon· SDE3Google· L5
Why interviewers ask: Simplification is harder than addition — anyone can add features; senior engineers cut. The interviewer wants evidence that you can identify accidental complexity, get team buy-in to remove it, and ship the simpler version without losing critical capability.
