## What is PyGrinder?

AI checks your Python code like a real FAANG interviewer. 50 tasks, 20-minute timer, detailed review. One purchase. No subscriptions.

Practice makes perfect — when you get instant, specific feedback on every solution. PyGrinder simulates the pressure of a real coding interview: strict timer, AI evaluation, and a verdict you can trust.

WHY 50 PROBLEMS MATTER:

Most interview prep apps give you 10-15 tasks. You memorize them in a weekend and run out. With 50 hand-picked Python problems — Easy to Hard, across every major topic — you build real algorithmic thinking, not muscle memory.

WHAT YOU GET:

• AI code review — analyzes structure, complexity, and patterns (not just "correct" or "wrong")
• 50 Python problems: Easy to Hard, no filler tasks
• 20-minute timer — real interview pressure
• Daily Challenge — one new task every day
• Detailed checklist: AI answers 5 specific questions about your solution
• Big O comparison: your complexity vs optimal
• Side-by-side code view with reference solution
• Actionable fix plan: what to change and why
• Filter by difficulty and topic (Arrays, Two Pointers, DP, Stack, Graphs, Heap...)

HOW IT WORKS:

1. Pick a problem or take the Daily Challenge
2. Write Python code in the built-in editor
3. Submit under the 20-minute timer
4. Get your verdict: PASS or FAIL with score (1-10)
5. See the exact line with the issue
6. Unlock full review, complexity analysis, and fix plan

PERFECT FOR:

• Junior Python developers preparing for technical screens
• CS students applying to internships
• Self-taught programmers who need structured practice
• Anyone improving algorithmic thinking

TOPICS: Arrays & Hashing, Two Pointers, Sliding Window, Stack, Binary Search, Linked List, Heap, Dynamic Programming, BFS & Graphs, Binary Tree, Design, Math, Bit Manipulation

One purchase unlocks everything. No subscriptions. No accounts. Just code, get reviewed, improve.

Download PyGrinder and walk into your interview ready.
