When is your interview?
Ready to start your prep?
Start Coding SessionYou've got 4 weeks until your technical interview at a top company. You open LeetCode, solve a random problem, feel good, then realize you've been doing this for months without a real plan. Sound familiar? The problem isn't effort—it's unfocused effort.
Coding interview preparation isn't just about grinding problems. It's about deliberate practice with strategic rest. The same cognitive science that makes the Pomodoro Technique effective for deep work makes it ideal for interview prep—where sustained attention, pattern recognition, and problem decomposition are everything.
The Interview Prep Focus Problem
Common Mistakes
- ×Grinding problems for 6+ hours without breaks
- ×Jumping between random topics without mastery
- ×Looking at solutions after 5 minutes of struggle
- ×Skipping behavioral and system design prep
Strategic Approach
- Structured 25-min sessions with mandatory rest
- Topic-focused practice blocks
- Struggle time before checking hints (20+ min)
- Balanced prep across all interview types
Pomodoro Strategies by Problem Type
Easy Problems
Arrays, Strings, Hash Maps
Medium Problems
Trees, Graphs, BFS/DFS, Binary Search
Hard Problems
Dynamic Programming, Advanced Graphs
System Design
Architecture, Scalability, Trade-offs
The 25-Minute Problem Solving Protocol
Read twice. Identify inputs, outputs, constraints.
Write approach before coding. Consider brute force first.
Implement solution. Talk through logic as you write.
Walk through with examples. Check edge cases.
Sample Daily Study Schedule
2x Hard DP/Graph problems, deep pattern analysis
3-4x Medium problems, review morning mistakes
System design reading, behavioral prep, pattern review
Long Break Strategy
Take 20-30 minutes after 4 pomodoros. Walk or do something non-screen. Your brain consolidates patterns during rest.
The Week Before Your Interview
Days 7-4: Review Mode
- Re-solve problems you struggled with
- Practice explaining solutions out loud
- 6 pomodoros max per day
Days 3-1: Light Practice
- Only 2-4 easy/medium problems
- Focus on behavioral story prep
- Sleep 8+ hours, no late grinding
Frequently Asked Questions
How many LeetCode problems should I solve per day?
Quality trumps quantity. 2-4 problems with deep understanding beats racing through 10 problems. A single hard problem where you struggle and learn is worth more than 5 easy problems you solve immediately.
Should I time myself when practicing?
Yes, but strategically. During learning, take time to understand. When closer to interviews, simulate real conditions: 20-25 min per medium, 35-45 min per hard.
How do I avoid burnout during prep?
The Pomodoro technique forces regular rest, preventing mental exhaustion. Also vary your study: mix coding with system design, behavioral prep, and mock interviews.
