Coding Interview Courses That Teach Patterns, Not Memorization

It depends on your timeline and fundamentals. With 2+ months and solid basics, start with Grokking the Coding Interview (the full 42-pattern curriculum). With under 6 weeks, take Grokking 75, the compressed track. If arrays, hash maps, or recursion feel shaky, begin with Grokking Data Structures & Algorithms before any patterns course. The full decision framework, by situation, is in our free timeline guide.

Patterns are reusable solution structures (like sliding window, two pointers, or tree BFS) that generate whole families of interview problems. Learning the pattern plus its tell prepares you for problems you have never seen, which is what interviews actually test. Our free complete guide to all 42 patterns explains each one.

Grokking the Coding Interview is a one-time $79 (discounted from $197) with lifetime access, and includes a free introductory tier so you can try the teaching style before paying anything. All courses are also available through the Design Gurus all-course subscription.

The full curriculum is roughly 90 hours: at 1.5 to 2 hours a day most learners finish in 8 to 12 weeks. On a shorter timeline, Grokking 75 covers the essential problems on a 6-week schedule, and our free 4-week plan shows the day-by-day structure.

Yes. Meta's AI-enabled round and Google's pilot both grade your ability to judge and verify code, which runs on the same pattern recognition the courses teach. Every loop also still includes classic no-AI rounds where pattern fluency is tested directly.
