面试准备

Systematic preparation for technical and behavioral interviews.

针对技术面试与行为面试的系统化准备方案。

Behavioral Frameworks

行为面试框架

STAR for Behavioral Questions

行为问题的STAR法则

Tell me about a time when...

Element	What to Cover
Situation	Context — project, team, timeline
Task	Your specific responsibility
Action	What YOU did (not the team)
Result	Quantified outcome, what you learned

请描述一次你……的经历

要素	涵盖内容
S情境	背景信息——项目、团队、时间线
T任务	你的具体职责
A行动	你个人的具体做法（而非团队整体）
R结果	可量化的成果，以及你学到的经验

Common Questions to Prepare

需提前准备的常见问题

"Tell me about yourself" → 60-second career narrative
"Biggest challenge/project" → STAR with technical depth
"Conflict with a teammate" → Show emotional intelligence
"Failure/mistake" → Honest story + what you learned
"Why this company?" → Research-driven, specific

“请介绍一下你自己” → 60秒职业经历简述
“你遇到过的最大挑战/项目” → 结合技术细节运用STAR法则作答
“与队友发生过的冲突” → 展现情商
“失败/失误经历” → 坦诚讲述故事+总结经验教训
“为什么选择我们公司？” → 基于调研，给出具体理由

Technical Interview Prep

技术面试准备

Coding

编码

Practice 2-3 problems daily (LeetCode medium)
Focus on: Arrays, Hashmaps, Trees, Graphs, DP
Always: Clarify → Brute force → Optimize → Code → Test
Think out loud — interviewer wants to hear your process

每天练习2-3道LeetCode中等难度题目
重点关注：数组、哈希表、树、图、动态规划（DP）
流程：澄清需求 → 暴力解法 → 优化方案 → 编码实现 → 测试验证
边思考边表达——面试官希望了解你的解题思路

System Design

系统设计

Practice these scenarios:

Design URL shortener (read-heavy, hashing, scaling)
Design chat system (WebSockets, persistence, presence)
Design news feed (fan-out, caching, ranking)
Design rate limiter (token bucket, sliding window, distributed)

练习以下场景：

设计URL短链接服务（读密集型、哈希算法、扩容方案）
设计聊天系统（WebSockets、持久化、在线状态管理）
设计信息流服务（扇出模式、缓存、排序算法）
设计限流服务（令牌桶、滑动窗口、分布式实现）
