## 工作流程

### 步骤 1: 提取原始信息
从JD文本中提取：
- 所有技能关键词
- 经验要求
- 教育要求
- 职责描述

### 步骤 2: 结构化分析
将提取的信息分类到：
```json
{
  "structured_analysis": {
    "required_skills": [...],
    "preferred_skills": [...],
    "responsibilities": [...],
    "minimum_qualifications": [...],
    "preferred_qualifications": [...]
  }
}
```

### 步骤 3: 技能匹配
对比用户基础简历（data/resume/base.json）：
```json
{
  "skill_match_analysis": {
    "matched_skills": [
      {"skill": "Python", "proficiency": "expert"}
    ],
    "partial_match_skills": [
      {"skill": "Java", "proficiency": "intermediate", "required": "advanced"}
    ],
    "missing_skills": [
      {"skill": "C++", "action": "需要学习基础"}
    ]
  }
}
```

### 步骤 4: 生成建议
基于匹配分析提供：
- 需要补充的技能
- 应该突出的经验
- 面试准备重点
- 简历优化建议

## 技能提取模式

### 编程语言识别
识别以下模式：
- "Proficiency in/with X"
- "Experience with/using X"
- "Strong knowledge of X"
- "X developer"
- "X, Y, or Z"

### 经验级别判断
- Entry: 0-2 years
- Mid: 2-5 years
- Senior: 5+ years
- Staff/Principal: 8+ years

### 系统设计关键词
- "Distributed systems"
- "Microservices architecture"
- "Scalable systems"
- "High-availability"
- "Large-scale systems"
- "Cloud-native"

### 软技能识别
- "Excellent communication"
- "Leadership experience"
- "Team player"
- "Problem-solving skills"
- "Self-motivated"

## 输出格式

### 公司信息文件更新
更新 `data/companies/{company}.json` 的 `job_descriptions` 部分：

```json
{
  "job_descriptions": {
    "pos_001": {
      "title": "Software Engineer III",
      "description_source": "...",
      "scraped_at": "2025-01-09T00:00:00Z",
      "raw_text": "完整JD文本...",

      "structured_analysis": {
        "required_skills": ["Python", "Distributed Systems"],
        "preferred_skills": ["Kubernetes", "ML"],
        "responsibilities": ["设计并开发软件"],
        "minimum_qualifications": ["计算机学位", "3年经验"],
        "preferred_qualifications": ["硕士", "5年经验"]
      },

      "skill_match_analysis": {
        "matched_skills": [...],
        "partial_match_skills": [...],
        "missing_skills": [...]
      }
    }
  }
}
```

## 使用示例

### 场景 1: 添加新公司时
用户提供JD文本，自动：
1. 提取所有技能和要求
2. 分析与用户简历的匹配度
3. 生成结构化分析报告
4. 保存到公司信息文件

### 场景 2: 简历优化前
为简历优化器提供：
- 关键技能列表
- 优先级排序
- 匹配度评分
- 优化建议

### 场景 3: 面试准备时
生成面试准备重点：
- 技术主题清单
- 可能的问题类型
- 需要深入研究的领域

## 匹配规则

### 完全匹配
- 用户有直接使用经验
- 项目中实际应用
- 可以深度讨论

### 部分匹配
- 了解相关技术
- 有相似技术经验
- 可以快速学习

### 缺失
- 完全没有经验
- 需要从头学习
- 建议学习路径

## 权重计算
用于匹配度评分：
- 必需技能：权重 2.0
- 优先技能：权重 1.0
- 加分项：权重 0.5

```
匹配度 = Σ(匹配等级 × 权重) / Σ(最大权重)
```

## 注意事项

1. **上下文理解**: 考虑JD的整体语境，而不是孤立的关键词
2. **技能归类**: 将不同名称但本质相同的技能归类
3. **公司特色**: 识别公司的技术文化（如Google重视可扩展性）
4. **隐含要求**: 识别JD中未明确表达的期望
5. **动态更新**: 随着用户技能提升，重新评估匹配度

## 高级分析功能（Phase 2新增）
