Interview Framework

访谈框架

Generate deep, non-obvious questions across these 10 dimensions:
从以下10个维度生成深度、非显而易见的问题：

1. Concurrency & Race Conditions

1. 并发与竞态条件

  • What if two users/processes do X simultaneously?
  • What happens during partial completion?
  • How do we handle interrupted operations?
  • What's the consistency model?
Example questions:
  • "If a user initiates this action and their auth token expires mid-way, should we preserve their progress or require re-authentication and restart?"
  • "Two users edit the same record simultaneously. Last-write-wins, first-write-wins, or conflict detection?"
  • "What if the background job is still processing when the user triggers the same action again?"
  • 若两个用户/进程同时执行操作X会发生什么？
  • 部分完成时会出现什么情况？
  • 如何处理中断的操作？
  • 采用何种一致性模型？
示例问题：
  • "如果用户发起操作后，认证令牌中途过期，我们应该保留其进度还是要求重新认证并重启操作？"
  • "两个用户同时编辑同一条记录，采用最后写入获胜、首次写入获胜还是冲突检测机制？"
  • "当后台任务仍在处理时，用户再次触发相同操作会发生什么？"

2. Failure Modes & Recovery

2. 故障模式与恢复

  • What if component X fails mid-operation?
  • How do users recover from errors?
  • What state is preserved on failure?
  • What are the retry semantics?
Example questions:
  • "The third-party API is down. Do we fail the entire operation, return partial results, or queue for retry?"
  • "Database write succeeds but cache invalidation fails. What's the consistency guarantee?"
  • "User uploads a file, processing starts, then storage quota is exceeded. What happens to the partial work?"
  • 若组件X在操作中途故障会发生什么？
  • 用户如何从错误中恢复？
  • 故障发生时会保留哪些状态？
  • 重试机制的规则是什么？
示例问题：
  • "第三方API宕机时，我们是终止整个操作、返回部分结果还是加入队列等待重试？"
  • "数据库写入成功但缓存失效失败，一致性保障是什么？"
  • "用户上传文件后处理开始，随后存储配额耗尽，已完成的部分工作会如何处理？"

3. Edge Cases & Boundaries

3. 边缘情况与边界

  • What happens at empty/zero/null states?
  • What are the maximum limits? What happens when exceeded?
  • What about the very first and very last items?
  • What about unicode, special characters, extreme lengths?
Example questions:
  • "What's the behavior when this list is empty? First item ever? Last item remaining after deletion?"
  • "The input contains 10 million records. Does the algorithm still work? What's the memory bound?"
  • "User submits the form with all optional fields empty. Is that valid?"
  • 空值/零值/Null状态下会发生什么？
  • 最大限制是多少？超出限制时会怎样？
  • 首个和最后一个条目会有什么特殊处理？
  • 如何处理Unicode、特殊字符、超长内容？
示例问题：
  • "当列表为空、是首个条目还是删除后仅剩最后一个条目时，行为分别是什么？"

  • "A power user wants to automate this via API. What would they expect the request/response to look like?"
  • "The feature name is X. Does that match what users actually call this action in their workflow?"
  • 用户如何理解该功能？
  • 哪些术语可能让用户产生混淆？
  • 用户有哪些未被规范提及的预期？
  • 用户的工作流上下文是什么？
示例问题：

7. Integration Effects

7. 集成影响

  • How does this affect existing features?
  • What other systems consume or produce this data?
  • What about undo/redo, search, notifications?
  • What webhooks or events should fire?
Example questions:
  • "This creates a new entity. Does search index update? Notifications fire? Analytics track it?"
  • "Undo/redo system - is this action reversible? How do we represent it?"
  • "Webhooks for integrations - what event payload should external systems receive?"
  • 这会对现有功能产生什么影响？
  • 还有哪些系统会消费或生成该数据？
  • 撤销/重做、搜索、通知功能会受影响吗？

Question Quality Guidelines

问题质量指南

Avoid obvious questions:

避免显而易见的问题：

  • "What color should the button be?"
  • "What's the error message text?"
  • "How many items per page?"
  • "Should we validate the input?"
  • "What fields are required?"
  • "What's the database schema?"
  • "按钮应该是什么颜色？"
  • "错误提示文本是什么？"
  • "每页显示多少条数据？"
  • "我们是否需要验证输入？"
  • "哪些字段是必填的？"
  • "数据库 schema 是什么？"

Generate deep questions that:

生成深度问题需满足：

  • Present specific scenarios, not abstract concepts
  • Surface second-order effects ("if X, then what about Y?")
  • Challenge unstated assumptions
  • Explore the boundaries of specified behavior
  • Consider adversarial or unexpected usage
  • Think about the feature's lifecycle (creation, usage, modification, deletion)
  • 呈现具体场景而非抽象概念
  • 挖掘二阶影响（“如果发生X，那么Y会怎样？”）
  • 挑战未明确的假设
  • 探索规范行为的边界
  • 考虑恶意或意外使用场景
  • 思考功能的全生命周期（创建、使用、修改、删除）

Convergence Detection

收敛检测

Track interview progress and detect convergence by:
  1. Novelty tracking: Each answer is analyzed for new concerns, requirements, or decisions
  2. Dimension coverage: Track which of the 10 dimensions have been explored
  3. Follow-up decay: If 2+ consecutive question batches yield no new significant concerns, offer to conclude
  4. User signal: User can always say "that covers it" to complete early
Interview Loop:
  dimensions_covered = []
  no_new_concerns_count = 0

  WHILE (has_new_concerns OR len(dimensions_covered) < 6):
    questions = generate_questions(unexplored_areas, previous_answers)
    answers = AskUserQuestionTool(questions)
    new_concerns = analyze_for_novelty(answers)
    update_coverage(answers, dimensions_covered)

    IF (new_concerns):
      no_new_concerns_count = 0
    ELSE:
      no_new_concerns_count += 1

    IF (no_new_concerns_count >= 2):
      offer_to_conclude()
      IF (user_confirms_done):
        BREAK
通过以下方式追踪访谈进度并检测收敛：
  1. 新颖性追踪：分析每个答案是否带来新的顾虑、需求或决策
  2. 维度覆盖：追踪已探索的10个维度
  3. 后续问题衰减：如果连续2轮问题未发现新的重要顾虑，提议结束访谈
  4. 用户信号：用户可随时表示“已覆盖所有内容”提前结束
Interview Loop:
  dimensions_covered = []
  no_new_concerns_count = 0

  WHILE (has_new_concerns OR len(dimensions_covered) < 6):
    questions = generate_questions(unexplored_areas, previous_answers)
    answers = AskUserQuestionTool(questions)
    new_concerns = analyze_for_novelty(answers)
    update_coverage(answers, dimensions_covered)

    IF (new_concerns):
      no_new_concerns_count = 0
    ELSE:
      no_new_concerns_count += 1

    IF (no_new_concerns_count >= 2):
      offer_to_conclude()
      IF (user_confirms_done):
        BREAK
