Coding interviews 评估解决问题和沟通能力,而不仅仅是得到正确答案。成功涉及清晰的方法(理解、规划、编码、测试)、全程沟通,以及有条理地处理问题。
结构化方法
text
1. UNDERSTAND the problem → clarify requirements, ask questions, confirm inputs/outputs,
edge cases (don't jump straight to coding)
2. PLAN → think through an approach; discuss it BEFORE coding; consider complexity/trade-offs
3. CODE → implement cleanly; explain as you go; write readable code
4. TEST → walk through with examples (incl. edge cases); find and fix bugs
→ a methodical approach shows engineering thinking (what they're really assessing).
