01 · Our story
Started the way most tools are: out of frustration.
LearnThatStack was founded by software engineers and technology enthusiasts who kept relearning the same lesson: interview preparation is scattered. The week before a technical round you're juggling stale bookmarks, a half-finished course, and a blog post from 2019 - none of it organized around what interviews actually ask.
Preparing for the interview shouldn't be harder than the interview.
So we built the resource we wanted for ourselves: interview questions organized by topic and difficulty, cheatsheets you can absorb in minutes, and refreshers for concepts that need quick re-up - plus a blog that writes up each video from our YouTube channel. And practice mode let you test your knowledge - with answer grading. Everything is written to help you learn, review, test your knowledge, and walk into your next interview with confidence.
02 · What makes us different
A few things we do on purpose.
The choices behind the platform - how content gets written, organized, and kept useful under deadline.
Structured
Everything is organized by topic and difficulty, so you can climb from fundamentals to advanced at your own pace - or jump straight to the level your interview demands.
Broad coverage
From development to DevOps, we cover the most in-demand skills with practical content - questions, cheatsheets, and refresher videos - grouped into focused categories.
From weeks out to the night before
Weeks to go? Drill questions topic by topic. A few days left? Hit the refreshers for a quick re-up. Night before? Use the cheatsheets for a fast review.
03 · Say hello
We read everything.
We're constantly expanding the library and improving the platform - and it's shaped by what you ask for. Suggestions, corrections, topic requests: send them over, or follow along as new content ships.
