Question

What deeper point about Design Patterns and SOLID should a senior Java developer mention?

  1. At senior level, the right answer is that Design Patterns and SOLID exists mostly for historical syntax reasons.
  2. Senior candidates should explain the tradeoffs of a pattern, especially around testability, coupling, lifecycle control, and accidental complexity.
  3. At senior level, the JVM removes the tradeoffs around Design Patterns and SOLID, so design choices barely matter.
  4. At senior level, any approach to Design Patterns and SOLID is equally correct if it compiles and passes a small test.

Hint

Look beyond syntax and explain the runtime, API, or design consequence.

Answer and rationale

Correct answer: B. Senior candidates should explain the tradeoffs of a pattern, especially around testability, coupling, lifecycle control, and accidental complexity.

Senior candidates should explain the tradeoffs of a pattern, especially around testability, coupling, lifecycle control, and accidental complexity. This is the kind of tradeoff-aware answer senior interviews usually expect.
