I wanted to share a free resource: https://crackingwalnuts.com

If you are from IT, computer science, engineering or you are a college student who wants to learn software engineering concepts or prepare for placements, internships, and interviews, this may help.

The site includes:

• DSA templates in Python, Java, and Go
• Low-level design problems and step-by-step design approaches
• System design walkthroughs
• Concurrency, Linux, databases, and backend engineering topics
• Company-specific preparation for Meta, Google, Amazon, OpenAI, and Anthropic
• Interactive tools to practice and understand concepts faster

The goal is to make software engineering learning more structured and practical, especially for college students and engineers who want to build strong fundamentals and prepare for real-world interviews.

It is completely free. Feedback is welcome.
