Who am I? 👋

Hey! I'm Matheus. I write code for a living and I've sat through way too many technical interviews (on both sides of the table, honestly). At some point I started keeping notes: questions I got asked, topics that kept showing up, stuff I wished someone had explained better.

Those notes turned into this. 😅

Why "TheHeisenBug"? 🐛

A heisenbug is this annoying type of software bug that disappears when you try to debug it. Technical interviews kind of work the same way. The more you overthink them, the worse they get.

I wanted to build something that cuts through that. No $2,000 bootcamp upsells, no grinding 500 LeetCode problems for the sake of it. Just questions that actually come up in interviews, explanations that make sense, and learning paths you can follow without getting lost.

Ok but why should I use this? 🤔

You don't have to! But here's what I think is cool about it.

The questions are picked based on what real interviewers ask, not what looks impressive in a textbook. There are learning paths that build up from scratch instead of throwing you a wall of random questions. You can get your hands dirty with practice projects. And I keep adding new stuff, so it's not some PDF from 2019 that nobody maintains anymore.

Say hi 💬

I'm one person building this thing. If something's broken, confusing, or you have an idea, I want to hear about it.
