Technical Mentoring
Core Principle
Your goal is to make yourself unnecessary.
A good mentor builds independence, not dependency. Every interaction should leave the mentee more capable of solving the next problem on their own.
The Mentoring Spectrum
TELL ←————————————————————————→ GUIDE
"Here's the answer" "What do you think the problem is?"
Default to the right side. Move left only when:
- They're truly blocked and time is critical
- The concept is foundational and needs direct explanation
- Safety or correctness is at risk
The Socratic Approach to Code Review
Instead of:
❌ "This is wrong, change it to X"
Try:
✅ "What happens if this value is null?"
✅ "What's the time complexity of this approach?"
✅ "What would happen under high load here?"
This builds reasoning skills, not just fixes the current bug.
Explaining Technical Concepts
The 4-Step Teaching Pattern
- Why it matters — connect to something they already care about
- Simple analogy — link to something familiar
- Minimal working example — smallest possible illustration
- Common mistake — the gotcha that trips everyone up
Calibrating Explanation Depth
- Too simple → they don't learn anything new
- Too complex → they lose the thread
- Ask first: "What's your current understanding of X?"
- Adapt to their answer
Code Walkthrough Structure
When walking someone through your code:
1. Start with WHY — what problem does this solve?
2. Show the data flow — input → process → output
3. Explain non-obvious decisions — "I chose X here because..."
4. Point out what you'd do differently now — models growth mindset
5. Invite questions at each step
Giving Feedback on Junior Code
The Feedback Ladder
- Acknowledge — find something genuinely good first
- Question — ask before telling ("What was your thinking here?")
- Suggest — "One approach I've used is..." not "You should..."
- Teach — explain the principle behind the suggestion
- Verify — "Does that make sense? What questions do you have?"
Feedback Anti-Patterns
- Rewriting their code entirely — kills ownership and learning
- Fixing without explaining — they'll make the same mistake next time
- Being vague — "make this cleaner" without showing how
- Only criticizing — not noticing what they did well
Tracking Mentee Growth
Periodically check in:
"What's one thing you can do now that you couldn't 3 months ago?"
"What's still confusing or intimidating?"
"What kind of support is most helpful from me?"
Adjust your approach based on their answers — what worked early may not work as they grow.
