Try a free mock interviewarrow_forwardFor absolute beginners, freeCodeCamp and Programming with Mosh are the best starting points. freeCodeCamp offers completely free, full-length courses that cover everything from HTML to Python. Mosh's courses are extremely polished and beginner-friendly. Once you're comfortable with basics, branch into language-specific channels like Corey Schafer for Python or Web Dev Simplified for JavaScript.
NeetCode is the consensus #1 for coding interview prep. His LeetCode pattern-based approach and structured roadmap (NeetCode 150) have helped thousands land offers at top tech companies. Pair NeetCode with Abdul Bari for deeper algorithm theory and Clément Mihailescu for real interview walkthroughs to cover all angles.
Yes. Many developers have landed their first jobs learning entirely from YouTube and free resources. The key is combining tutorials with actual practice: build projects, solve LeetCode problems, and contribute to open source. YouTube gives you the knowledge, but you need to apply it. Channels like freeCodeCamp and Traversy Media provide enough depth to go from zero to job-ready.
For system design specifically, check out Hussein Nasser for backend deep dives and ByteByteGo (Alex Xu) for visual system design breakdowns. ThePrimeagen also touches on architecture and performance topics that overlap with system design thinking. For structured prep, Gaurav Sen's channel is another solid pick.
Don't just watch. Code along. Pause the video, try to solve the problem yourself first, then watch the solution. Take notes on patterns, not solutions. Use channels like NeetCode for structured learning (follow the roadmap), not random browsing. Limit passive watching to 30-60 minutes, then spend 2-3x that time actively coding what you learned.
