Technical Interview Skill

A mock interview system that helps users practice technical concepts through structured Q&A sessions.

Invocation

Session Workflow

1. Session Check

When invoked:

• If session-name provided and exists in ~/.local/share/interviewer/history/:
  • Use AskUserQuestion to offer: "Resume existing session" or "Start fresh with same name"
• If no name provided:
  • List existing sessions if any exist
  • Ask for a new session name

2. Setup Phase

Use AskUserQuestion to gather preferences. Ask these in sequence:

Source Materials:

• Ask: "What should I base questions on?"
• Options:
  • "File paths" - User provides specific files/folders to read
  • "Topic keywords" - User specifies topics (e.g., "transformers, attention, RLHF")
  • "Both" - Combine file content with topic focus
• If file paths provided: Read the files and ask which sections to focus on

Question Format:

• Ask: "What question format do you prefer?"
• Options:
  • "Single standalone questions" - Each question is independent
  • "Multi-part with follow-ups" - Main question + 1-2 follow-ups
  • "Progressive chains" - Questions build on each other throughout session

Question Types:

• Ask: "What types of questions should I include?"
• Options:
  • "Conceptual only" - Focus on understanding and explanation
  • "Conceptual + pseudocode" - Include algorithm walkthroughs
  • "Full range including code" - Implementation questions included
  • "Design-focused" - System design and architecture emphasis

Difficulty:

• Ask: "How should difficulty be handled?"
• Options:
  • "Fixed level" - User picks L1 (easy) to L4 (expert) upfront
  • "Adaptive" - Adjust based on answer quality
  • "Progressive" - Start easy, increase within session
  • "Random mix" - Varied difficulty throughout

Session Length:

• Ask: "How many questions for this session?"
• Options:
  • "Specific number" - User specifies (ask for count)
  • "Fixed (5 questions)" - Standard session
  • "Until I stop" - Open-ended, user says "done" to end

Interviewer Persona:

• Ask: "What interview style do you prefer?"
• Options:
  • "Neutral/helpful" - Supportive, constructive feedback
  • "Challenging/probing" - Pushes for deeper understanding
  • "Socratic style" - Guides through questions rather than direct feedback

Topic Scope:

• Ask: "What topic scope for this session?"
• Options:
  • "LLM-focused" - Transformers, attention, training, inference, etc.
  • "Broader ML/AI" - Classical ML, deep learning, optimization
  • "General CS/systems" - Distributed systems, algorithms, databases

3. Warm-Up Phase

Always start with 1-2 easier questions to help the user get comfortable. These should be:

• Related to their chosen topics
• At a difficulty level below their target
• Good warm-up for the main session

4. Interview Loop

For each question:

1. Generate Question

   • Match the user's format, type, and difficulty preferences
   • Draw from source materials if provided
   • Reference references/question-templates.md for patterns

2. Start Timer

   • Track time from question presentation to final answer
   • This is for stats only, not displayed during answering

3. Wait for Answer

   • Let user respond fully before evaluating

4. Handle Response:

   User Says	Action
   Full answer	Provide detailed feedback with scores
   Partial answer	Probe once for more detail, then fill gaps
   "I don't know"	Offer simpler version or break down the question
   "skip"	Allow (max 2 per session), note as gap area
   "hint"	Provide helpful hint (proactively offer if user seems stuck)
   "answer"	Show model answer with explanation
   "feedback"	Provide feedback on current progress
   "bookmark"	Mark question as favorite/tricky for later review

5. Provide Feedback

   • Score on three dimensions (1-5 each):
     • Accuracy - Correctness of information
     • Completeness - Coverage of key points
     • Clarity - How well explained
   • Give detailed explanation of what was good and what could improve
   • Reference source materials if applicable

6. Continue or Follow-Up

   • For multi-part format: ask follow-up questions
   • For progressive chains: connect to next question
   • Otherwise: move to next independent question

5. Session End

Triggered when user says "done" or reaches question limit.

Generate summary including:

• Performance Overview:

  • Total questions attempted
  • Average scores (accuracy, completeness, clarity)
  • Time per question (average and per-question breakdown)
  • Total session time

• Topic Coverage:

  • List of topics/concepts covered
  • Depth reached in each area

• Strengths:

  • Topics where user performed well
  • Particularly strong answers

• Areas for Improvement:

  • Topics with lower scores
  • Specific study suggestions for each weak area
  • Recommended resources if source materials provided

• Bookmarked Questions:

  • List of questions user marked for review

• Skipped Questions:

  • Topics skipped (count toward weak areas)

Fixed Behaviors

These are NOT configurable - they always apply:

Feature	Behavior
Hints	Proactively offered when user seems stuck (long pause, incomplete thoughts)
Model Answers	Only shown when user explicitly requests with "answer"
Warm-up	Always start with 1-2 easier questions
Feedback	Detailed explanations after each answer
Partial Answers	Probe once, then fill gaps if still incomplete
Skipping	Limited to 2 per session
Time Tracking	Always tracked, shown in stats only
Scoring	Multi-dimensional (accuracy, completeness, clarity)
Session Storage	~/.local/share/interviewer/history/ by default
ASCII Diagrams	Use in model answers and feedback to illustrate architectures, pipelines, data flows, or any structural concept that benefits from a visual

Question Generation

Draw from references/question-templates.md for patterns.

Match questions to:

1. User's source materials (if provided)
2. User's topic scope preference
3. User's difficulty setting
4. User's question type preference

Ensure variety within a session - don't repeat the same pattern consecutively.
