Preparation Guide
A systematic approach to preparing for behavioral interviews
Phase 1: Brain Dump
Goal
Get ALL your experiences on paper. Don't filter yet - just capture everything.
Instructions
- Open a Google Doc or notebook
- For each core quality, brainstorm:
- Leadership & Initiative
- Resilience
- Teamwork
- Influence & Persuasion
- Integrity & Ethics
- Think about:
- Work projects
- School projects
- Personal projects
- Volunteer work
- Everyday situations
- Don't judge yet - write everything down
Remember
Phase 2: Story Selection
Create Your Story Matrix
For each quality, identify 2-3 strong stories. Rate them on three axes:
| Story | Personal Involvement | Business Impact | Scope |
|---|---|---|---|
| Example Project A | High | High | Appropriate |
| Example Project B | Medium | High | Appropriate |
Selection Criteria
- Personal Involvement: Were you central to the story? Not just "I was in the room."
- Business Impact: Measurable difference? Revenue, user experience, costs, performance?
- Scope: Appropriate for your level? (See Questions page for level guidelines)
Target: 10-15 Total Stories
- 2-3 per quality (minimum)
- Some stories can cover multiple qualities (have backups!)
- Quality over quantity
Phase 3: Story Crafting
Use CARL Framework
For each selected story, write out using Context โ Action โ Result โ Learning
Story Worksheet Template
Story: [Title]
Qualities Demonstrated: [List]
Context (10-20%)
- Where/when did this happen?
- Who was involved?
- What was the challenge?
Action (60%) โญ MOST IMPORTANT
- What specific steps did YOU take?
- Why did you do it that way?
- What decisions did you make?
- How did you collaborate?
Result (10-20%)
- Business impact (metrics if possible)
- Relationship outcomes
- What changed?
Learning (10%)
- What did you learn?
- How did you apply it next time?
- What would you do differently?
Key Principles
- Show, don't tell: Describe actions, not qualities
- Focus on YOU: What did YOU do, not the team?
- Be specific: "I surveyed 15 analysts" not "I asked some people"
- Include obstacles: Real stories have challenges
Phase 4: Practice
The Critical Mistake Most People Make
They write beautiful paragraphs and try to memorize them. This makes you sound scripted.
Better Approach: Bullet Points
- Write your story as bullet points (5-7 bullets max)
- Practice speaking from bullets only
- Force yourself to form sentences naturally
- This creates natural flow, not memorization
Practice Methods
1. Self-Recording
- Record yourself answering questions
- Watch/listen back (you'll cringe - that's good!)
- Identify filler words (um, like, you know)
- Notice body language and eye contact
- Replace filler words with pauses
2. Mock Interviews
- Practice with friends or coaches
- Get feedback on clarity
- Practice handling follow-up questions
- Simulate real interview pressure
3. Flash Cards
- Write common questions on cards
- Shuffle and practice randomly
- Tests your ability to think on your feet
- Reduces anxiety by building confidence
Phase 5: Company-Specific Prep
Research Company Values
Most companies publish their values. Examples:
- Amazon: 16 Leadership Principles
- Meta: Values like "Move Fast", "Be Bold", "Focus on Impact"
- Google: "Googleyness" principles
Map Your Stories to Values
For each company value, identify which of your stories demonstrates it:
Example: Amazon's "Ownership"
- Story 1: Taking responsibility for cross-team issue
- Story 2: Thinking long-term despite pressure
- Story 3: Acting on behalf of entire company
Prepare Company-Specific Questions
- "Why do you want to work here?"
- "What excites you about this role?"
- Research the team/product/company deeply
- Connect your goals to their mission
Phase 6: The Three Must-Prepare Questions
1. Tell Me About Yourself
Time: 2-2.5 minutes
Structure:
- Brief description + personal twist (30 sec)
- List of accomplishments (60-90 sec)
- Forward-looking statement connecting to role (30 sec)
Practice: Until it sounds natural (not memorized)
2. Your Favorite/Most Impactful Project
Time: 5-7 minutes if detailed
Choose based on:
- High personal involvement
- High business impact
- Appropriate scope for your level
- Demonstrates multiple qualities
Prepare: Expanded CARL format with details
3. Conflict Story
Why Critical: Almost every interview asks about conflict
Must Include:
- Seeking to understand first
- Showing empathy
- Using objective data
- Right communication channel
- Win-win solution
- Relationship preserved
Phase 7: Handling Questions You Didn't Prepare For
The Three-Step Process
Step 1: Decode
What is the question really asking?
- Clarifying: "What metrics?" โ Answer directly
- Digging: "Did anyone have conflicts?" โ They want conflict resolution signal. Go deeper.
Step 2: Select
Choose the best story. If none fit perfectly:
- Propose a pivot: "I haven't had exactly that situation, but I have a similar story about [related quality]. Can I share that?"
- Most interviewers will say yes if it's related
Step 3: Deliver
Use your prepared structure (CARL). Guide the conversation back if needed:
- "I think we've covered that well. Should we talk about the technical implementation phase?"

Questions to Ask the Interviewer
Why This Matters
Interviewers assess you based on what you ask. Good questions show:
- You've thought about the role
- You understand what matters
- You're evaluating fit (not just desperate)
Great Questions
- For Hiring Managers: "What's your management style? How do you help engineers grow? What makes engineers successful on your team?"
- For Team Members: "What are the biggest technical challenges the team faces? How does the team make technical decisions? What's the product direction?"
- For Any Interviewer: "What does success look like in this role? What are you most excited about in the next 6 months?"
Questions to Avoid
- โ "What's a day in the life?" (too generic)
- โ "What's the salary?" (save for recruiter)
- โ "How many hours do people work?" (signals wrong priorities)
Preparation
Prepare 5-10 questions. You won't ask them all, but having options shows thoughtfulness.
Why Preparation Matters: The Data
The Critical Finding
According to former Meta Engineering Managers:
"90% of success in behavioral interviews comes from preparation. Most people spend all their time on technical interviews, but behavioral interviews are actually the #1 interview type that is underprepared for. If you get good at behavioral interviewing, you will actually become a better engineer because you'll understand what's made your projects successful."
Two Benefits of Behavioral Prep
- Interview Success: You'll deliver stories with confidence and hit all the signals interviewers are looking for
- Career Growth: Understanding what makes your work successful helps you repeat those behaviors. It's like writing a performance review - the reflection helps you apply those learnings going forward
The Three Questions You MUST Prepare
1. "Tell Me About Yourself"
Why critical: This is often the FIRST question. First impressions matter. Interviewers are most attentive in the first 5-10 minutes.
Structure (2-2.5 minutes total):
- Part 1 (30 sec): Brief description + personal twist
- Part 2 (60-90 sec): List of 3-5 accomplishments (NOT a history lesson)
- Part 3 (30 sec): Forward-looking statement connecting to the role
Practice until:
- It sounds natural (not memorized)
- You can deliver it confidently without notes
- It flows smoothly from one part to the next
- You can adapt it slightly based on the role
2. Your Favorite/Most Impactful Project
Why critical: Almost every interview asks about a project. This sets the stage for your entire interview.
Choose based on:
- High personal involvement (you drove it)
- High business impact (measurable results)
- Appropriate scope for your level
- Demonstrates multiple qualities
Prepare in detail:
- Full CARL format
- 5-7 minutes if you're a good speaker
- Be ready to dive deep into any part
- Have answers for common follow-ups ready
3. A Conflict Story
Why critical: Almost every interview asks about conflict. You WILL get this question.
Must include:
- โ Seeking to understand first
- โ Showing empathy
- โ Using objective data
- โ Right communication channel
- โ Win-win solution
- โ Relationship preserved
Common follow-ups to prepare for:
- "How did you feel during this?"
- "What if they hadn't agreed?"
- "How do you prevent this in the future?"
Advanced Preparation: Story Mapping
Create Your Story Matrix
Build a mental map (or actual document) that helps you quickly select the right story:
| Quality | Story 1 | Story 2 | Story 3 |
|---|---|---|---|
| Leadership | Organized team event | Led feature project | Mentored junior |
| Resilience | Failed project recovery | Orchestra story | Deadline challenge |
| Teamwork | Cross-functional project | Disparate backgrounds | Resolved team conflict |
| Influence | PitchBook story | Convinced PM | Changed architecture |
| Integrity | UPS timekeeping | Ethical code review | Raised process issue |
Why this matters: During the interview, you can quickly look at your matrix, identify which quality is being tested, and select the best story. This reduces panic and helps you stay organized.
