Real Coding Interview Questions & Solutions from Top Tech Companies

Welcome! This repository is a curated collection of real coding problems, algorithm tasks, and technical screening questions I personally solved during interview processes with top tech companies.

Each subfolder contains:

• Company-specific coding tasks (e.g., Meta, Goldman Sachs, Adyen)
• My own optimized or quick-to-submit solutions
• Multi-language implementations (when applicable)
• Follow-up refinements based on well-known sources like GeeksForGeeks, LeetCode, JournalDev, and more.

Why This Repository?

• Fast-track your interview prep with real-life coding examples
• Compare multiple strategies: fast-to-submit vs. deeply optimized
• Practice algorithms, data structures, and problem-solving
• Contributions welcome: improve or refactor any solution

Repository Structure

• Each folder = one company (e.g., /Meta/, /GoldmanSachs/)
• Inside: the questions I faced + my coded solutions
• Languages used include Python, Java, C++, and more
