Mentoring Developers

This skill provides frameworks for effective mentoring, knowledge transfer, and developing other engineers.

When to Use This Skill

• Starting a formal or informal mentoring relationship
• Onboarding a new team member
• Teaching technical concepts to junior engineers
• Running effective 1:1 meetings
• Pair programming with less experienced developers
• Helping someone navigate their career

Core Frameworks

Crawl-Walk-Run Progression

A framework for teaching new skills progressively:

Example: Teaching Code Review

Crawl: You review PRs together, thinking aloud about what you look for, why things matter, what makes good/bad code.

Walk: They do the review, you watch. You ask questions: "What about this section?" You course-correct in real-time.

Run: They review independently. You spot-check occasionally and discuss any disagreements. They come to you with edge cases.

Key principle: Stay in each phase long enough. Rushing to "Run" creates gaps.

Socratic Questioning

Instead of giving answers, ask questions that lead to understanding:

Benefits

• They learn to think, not just memorize
• Builds problem-solving muscles
• They discover answers themselves (more memorable)
• You understand their thought process

When NOT to use Socratic questioning:

• Production incident - just tell them the fix
• Simple factual questions - don't make them guess
• When they're frustrated or overwhelmed

Building Trust

Trust is the foundation of effective mentoring:

Trust-Building Practices

1. Show genuine interest in their goals

   • Ask about career aspirations
   • Remember and follow up on personal details
   • Celebrate their wins publicly

2. Create psychological safety

   • Normalize mistakes: "I make these too"
   • Share your own failures and learnings
   • Never shame, even privately

3. Maintain confidentiality

   • What they share stays between you
   • Don't mention their struggles to others
   • Ask before sharing their work as examples

4. Be consistent and reliable

   • Show up to 1:1s on time
   • Follow through on commitments
   • Be honest about your own limitations

5. Acknowledge when they teach you

   • Mentoring is bidirectional
   • Let them know when you learned from them
   • Builds their confidence and equalizes the relationship

Tailoring to Learning Styles

People learn differently. Adapt your approach:

Most people are a mix. Start with all approaches, then observe what clicks.

Pair Programming for Mentoring

Pair programming is a powerful mentoring tool when done well. See references/pair-programming-guide.md for detailed guidance.

Key Principles

• Rotate driver/navigator roles
• Narrate your thinking when driving
• Let them struggle (productively)
• Never grab the keyboard without permission

1:1 Meeting Structure

Effective 1:1s are the backbone of mentoring. See references/one-on-one-structure.md for detailed templates.

Basic Structure (30 min)

• Progress check (5 min)
• Challenges/blockers (10 min)
• Development goals (10 min)
• Open discussion (5 min)

Key Principles for 1:1s

• Their agenda, not yours
• Consistent cadence (weekly ideal)
• Take notes and follow up
• Occasionally skip status and go deep on growth

Common Mentoring Mistakes

Taking Over

❌ Grabbing the keyboard when they struggle ✅ Ask guiding questions, let them try

Assuming Knowledge

❌ "You know what a REST API is, right?" ✅ "What's your experience with REST APIs?"

Overwhelming with Information

❌ Explaining everything about microservices at once ✅ Focus on what they need now, save rest for later

Neglecting the Relationship

❌ Only discussing technical work ✅ Check in on how they're doing personally

Doing vs. Teaching

❌ "I'll just fix this, it's faster" ✅ "Let's fix this together so you see how"

Measuring Progress

Track mentee development over time:

Technical Progress

• PRs requiring less revision
• Taking on more complex tasks
• Helping others with areas you taught

Professional Progress

• More confident in meetings
• Asking better questions
• Navigating team dynamics effectively

Relationship Health

• They bring you problems early
• Honest about struggles
• Proactive about scheduling time
