How AI Transforms Interview Prep
Traditional prep: buy a book, grind through 200 fixed problems, hope the ones you practiced come up. AI-powered prep: generate problems targeted to your specific gaps, get step-by-step hints without spoilers, explain why a solution works — not just that it works.
Your DSA Practice Partner Setup
You are my technical interview coach. I am preparing for
software engineering interviews at mid-tier tech companies.
My current level: [beginner / intermediate / advanced]
Topics I struggle with: [e.g., "dynamic programming, graphs"]
Language preference: Python
Generate a LeetCode-style problem that:
- Tests [specific topic]
- Is at [Easy/Medium] difficulty
- Has a clear, realistic problem statement
- Includes 2-3 example test cases
After I attempt it, you will review my solution and:
1. Identify bugs without giving away the fix
2. Ask me what the time/space complexity is
3. Show me the optimal solution only after I've attempted one
I've been stuck for 15 minutes. Give me a hint that:
- Does NOT reveal the algorithm
- Asks me a question that points me in the right direction
- Explains what pattern this problem falls into
My current thinking: [describe your approach so far]
Review my solution:
[PASTE YOUR CODE]
Tell me:
1. Does it pass all test cases? Walk through each.
2. What is the time complexity? Space complexity?
3. What would a senior engineer say about the code quality?
4. How would you optimize this if performance mattered?
5. What is the most elegant solution to this problem?
The 14 DSA Patterns That Cover 80% of Problems
- Two pointers, sliding window, fast/slow pointers
- Binary search (on sorted arrays and on answers)
- Tree/graph traversal: BFS, DFS, backtracking
- Dynamic programming: top-down, bottom-up, 1D and 2D
- Heap / priority queue, monotonic stack
- Merge intervals, trie, union find
ℹ️
The pattern approach: When you see a new problem, identify its pattern before writing any code. Ask Claude: "What pattern does this problem use?" until you can identify patterns yourself. Pattern recognition is the actual skill being tested.
Day 1 Exercise30-Minute DSA Practice Session
- Set up the DSA coach prompt with your level and weak topics.
- Request one Easy and one Medium problem.
- Attempt each problem for 20 minutes max. If stuck, use the hint prompt.
- After each solution, run the review prompt on your code.
- For each problem: write down the pattern it used in your notes.
Day 1 Summary
- Use AI to generate targeted problems at your level, not random problem grinding.
- Request hints that point direction without giving answers — maintain the learning benefit of struggle.
- Always have your solution reviewed: correctness, complexity, quality, and the optimal approach.
- Track which patterns you see — 14 patterns cover 80% of problems you will face.
