My Journey Through 1,000+ LeetCode Problems, and What I Learned

I still remember the sting of my first failed technical interviews. I thought I was prepared - I was studying at a top CS school (UC Berkeley), had a solid GPA, and I was passionate about coding. But when it came time to face the whiteboard, I froze. The problems seemed insurmountable, and my mind went blank. I left those interviews feeling defeated and questioning my abilities.

That failure turned into a promise to myself—some might call it an obsession. I wanted to build myself up to be invincible. I wanted to prepare myself to a point where I could not fail. I dedicated myself to solving LeetCode problems, and before I knew it, I had completed over 1,000 of them. While I did better at interviews after that, I still felt like something was missing. I could solve problems, but I didn't truly understand the underlying principles. I was basically a robot, cranking through problems without making connections or recognizing patterns. I was still struggling to explain my thought process clearly, and I often found myself second-guessing my solutions.

Then, I dedcided to take a slower approach. I started to see patterns in the problems, to recognize the common themes that ran through them. It was like a fog had lifted, and I could finally see the big picture. I realized that many of these problems were just variations on a theme, and once you understood the core concepts, you could tackle almost any problem with confidence. It was this whole new way of thinking that I had been missing. I began to approach problems with a deeper understanding, breaking them down into their fundamental components and building up from there.

I started to see the connections, the underlying principles that tied everything together. It was like learning to see the matrix, if you will. This course is the culmination of that journey. It's the system I developed to go from failing interviews to receiving offers from Google, Meta, Snap, Airbnb, Uber, and more. It's designed to help you build that same deep, intuitive understanding, so you can walk into any interview with the confidence that you're ready for whatever they throw at you.

This is more than just a course; it's the roadmap that I wish I had when I started.

Yours truly,
