问题：[具体技术不足]
根本原因：[为什么会出现这个问题]

改进计划：
1. 短期（1-2周）：
   - [具体学习内容]
   - [练习题量]
   - [验证方式]

2. 中期（3-4周）：
   - [深化内容]
   - [实战项目]
   - [总结归纳]

推荐资源：
- 书籍：[推荐书籍]
- 在线课程：[课程名称]
- 练习平台：[LeetCode/牛客等]
- 视频教程：[推荐视频]

问题：[具体沟通不足]
改进方法：

练习策略：
1. Think Aloud 练习
   - 边思考边说出来
   - 录音回听改进
   - 找人模拟练习

2. 结构化表达
   - 使用总-分-总结构
   - 先说结论再展开
   - 使用第一、第二、第三

3. 主动确认
   - 定期确认理解
   - 询问是否需要澄清
   - 征求反馈

相似度 = 文本相似度 × 0.7 + 关键词重叠度 × 0.3

其中：
- 文本相似度：描述文本的语义相似度（使用embedding）
- 关键词重叠度：关键词/术语的重叠比例

判定阈值：≥ 0.75

新不足："动态规划状态转移方程推导困难"
历史不足："DP问题无法独立设计状态"
相似度：0.82 → 判定为重复

priority = (frequency_score × 0.3 + severity_score × 0.3 + impact_score × 0.2 + status_weight × 0.2) × 10

## 面试心态指南

### 正确的心态 ✅
1. **学习机会**: 将面试视为学习和改进的机会
2. **平等对话**: 面试是双向选择，你也在评估公司
3. **展现真我**: Be authentic, 不要过度表演
4. **信任准备**: 相信自己充分准备的能力
5. **享受过程**: 展示你的热情和技术兴趣

### 错误的心态 ❌
1. **完美主义**: 不可能完美，专注发挥最好水平
2. **过度紧张**: 紧张是正常的，适度紧张有助于专注
3. **比较心理**: 每个人路径不同，专注自己
4. **结果焦虑**: 一次面试不能定义你的价值
5. **讨好面试官**: 要专业，但不要卑躬屈膝

### 焦虑管理技巧
**面试前**:
- 深呼吸: 4-7-8呼吸法 (吸气4秒, 屏息7秒, 呼气8秒)
- 积极想象: 想象成功的场景
- 准备清单: 确认所有材料就绪
- 早到: 提前10-15分钟到达

**面试中**:
- 问题听不懂: 礼貌地请求clarify
- 卡住了: 诚实地说"Let me think", 不要慌张
- 出错了: 承认错误, 解释如何修正
- 时间压力: 专注当前步骤, 不要想太多

**面试后**:
- 记录: 立即记录问题和你的回答
- 复盘: 客观分析哪些做得好/不好
- 放下: 不要纠结，准备下一个
- 感谢: 发感谢信给面试官
