Question

What deeper point about Topological Sort should a senior Java developer mention?

  1. At senior level, the right answer is that Topological Sort exists mostly for historical syntax reasons.
  2. At senior level, the JVM removes the tradeoffs around Topological Sort, so design choices barely matter.
  3. The deeper interview answer is that the ordering exposes dependency structure, which is why both indegree-based and DFS-based solutions work.
  4. At senior level, any approach to Topological Sort 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: C. The deeper interview answer is that the ordering exposes dependency structure, which is why both indegree-based and DFS-based solutions work.

The deeper interview answer is that the ordering exposes dependency structure, which is why both indegree-based and DFS-based solutions work. This is the kind of tradeoff-aware answer senior interviews usually expect.
