No videos. On purpose.

This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on tech interview you can find — even without producing a single minute of custom video.

Practitioner-tested, not vendor marketing

This course is built by engineers who ship tech interview systems in production. It reflects how these tools actually behave at scale.

Code you can run, not demos to watch

Every day includes working code examples you can copy, run, and modify right now. Understanding comes through doing.

Links to the canonical sources

Instead of re-explaining existing documentation, this course links to the definitive open-source implementations and the best reference material on tech interview available.

Completes in 5 one-hour sessions

Each day is designed for about an hour of focused reading plus hands-on work. Do the whole course over a week of lunch breaks. No live classes, no quizzes.

The 5 Days

Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.

01Day One

Arrays, Strings, and Hash Maps

The most common interview patterns — two pointers, sliding window, frequency counting with hash maps, and the string manipulation questions that appear in 40% of first-round screens. Using AI to generate variations and explain edge cases.

02Day Two

Trees, Graphs, and Recursion

Binary tree traversals (BFS/DFS), common tree interview patterns (diameter, LCA, path sum), graph representations, BFS for shortest path, DFS for connected components, and the recursion-to-iteration translation technique.

03Day Three

Dynamic Programming Patterns

The six DP patterns that cover 90% of DP interview questions: 0/1 knapsack, unbounded knapsack, longest common subsequence, matrix path, interval, and subsequence. Memoization vs tabulation and when each is cleaner.

04Day Four

System Design Interviews

The 45-minute system design framework, the components every system design answer needs (load balancers, databases, caches, queues), how to handle capacity estimation, and the system design question types that appear at FAANG vs startup interviews.

05Day Five

Behavioral Questions and Offer Strategy

STAR method for behavioral answers, the 12 most common behavioral questions and how to answer them, negotiating offers (data-backed ranges, competing offers, equity vs salary), and using AI to rehearse answers before real interviews.

The best external videos on this topic.

Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.

Read the source.

The best way to deepen understanding is to read the canonical open-source implementations. Clone them, trace the code, understand how the concepts in this course get applied in production.

Three kinds of people read this.

Engineers Preparing for FAANG or High-Growth Startups

The technical interview process has a specific format. This course teaches the format and the problem-solving patterns — not just individual problem solutions.

Self-Taught Engineers Filling Gaps

Self-taught engineers often have practical skills but gaps in the theoretical CS topics interviewers test. This course identifies and fills those gaps efficiently.

Engineers Returning After a Gap

Coming back after parental leave, layoff, or career pivot? This course gets you back to interview readiness in 5 focused days.
