Deep dives into data structures, algorithms, and interview preparation. Written by engineers who have been there.
The only guide to FAANG interviews you need. Master the 14 patterns, behavioral frameworks, and system design basics in one structured plan.
Discover why you forget solutions and the cognitive science behind pattern retention. Learn how spaced repetition and contextual learning can transform your interview prep.
You solved the problem yesterday, but today your mind is blank. Understand why this happens and what you can do about it.
The #1 interview skill is pattern recognition. Learn the signals that indicate which algorithm to apply.
You understand the solution when you see it, but cannot produce it yourself. This is the recognition vs recall problem.
You have solved 500+ problems but still fail interviews. The problem is not quantity, it is strategy.
The debate between memorization and understanding. Learn when memorization helps and when it hurts.
Most "gamified" platforms just use streaks and badges. Discover how true narrative-driven learning can transform your interview prep.
The complete 12-week roadmap to mastering Data Structures and Algorithms. Week-by-week curriculum from Big O basics to Dynamic Programming.
Stop learning topics randomly. Follow a proven curriculum sequence that builds concepts in the right order.
Stop asking 'how long' and start planning. Realistic, battle-tested timelines for beginners, CS grads, and rusty seniors.
Practical time management strategies for engineers who need to prepare without burning out.
Master the science of learning. Spaced repetition, active recall, and interleaving—the evidence-based techniques top engineers use to retain algorithms permanently.
How to apply the most effective learning technique to algorithm study. Stop relearning the same concepts.
Why you forget algorithms and how Feynman's 4-step method, enhanced with AI, builds deep understanding that survives interview pressure.
Learn algorithms through interactive visualizations. Watch code execute line-by-line with synchronized animations for sorting, searching, graphs, trees, and dynamic programming.
Watch binary search execute line-by-line with synchronized code highlighting and array visualization.
Watch linear search scan through an array element by element until it finds the target value.
Watch jump search skip ahead in blocks of sqrt(n), then linear search within the block where the target lies.
Watch interpolation search estimate the target position based on value distribution, achieving O(log log n) on uniform data.
Watch exponential search find the range by doubling, then binary search within that range for O(log n) performance.
These articles are just the beginning. Our full course combines story-driven learning with spaced repetition for lasting retention.
