A. Validate formats and invariants at the first responsible boundary so later code can rely on the data honestly. This is one of the clearest beginner-to-mid interview signals because it reveals system thinking.
Why
Interviewers usually care less about keywords than about whether you can explain why the code is shaped the way it is.
