I Built an Interview Prep Tool Instead of Grinding LeetCode

I am currently preparing for Software Engineer interviews. Like many developers, my first instinct was to open LeetCode and start grinding problem...

Wow, Julien, I'm absolutely blown away by the sheer genius of your interview prep tool. You finally made it real!! I mean, who needs to spend hours on LeetCode problems when you can create something that helps people really grasp the underlying ideas? The fact that it's open-source and can be used locally or on Vercel is just the cherry on top. I'm seriously considering using this in my own prep routine, do you think it would be possible to add some kind of community feature for users to share their own templates or pattern flashcards?

Thanks Aryan!
Exactly, I am happy that you are aligned with my approach here.
Feel free to use the tool! I am currently using it for my own interview prep.
Yeah definitely, it could be interesting to add this community feature if its valuable to you and others. I can look into it.

I practice interview situations by explaining how I solve coding challenges daily (one from CodeWars and one from freeCodeCamp). I even record myself and from there I can avoid some bad habits I never would have found if it was not caught on camera. Been doing it a while now and I can honestly see some improvements on my side.

Here's my current video files:

PS. It's nice that I could compare my progress against my old videos.

This is a very smart approach Elmar! I can definitely see the value of explain-back situations here and being able to observe improvements over time that simulate an interview scenario

Julien, this is great timing. I was actually looking for something that focuses more on patterns and reasoning rather than just grinding through problem after problem.

Thanks for sharing this. I'll give it a look, and good luck with the interviews.

Love this approach! 🧠 Grinding 200 random LeetCode problems usually just leads to short-term memorization, whereas mastering 20 core patterns gives you a framework to solve literally anything thrown at you.

Exactly! I wanted to develop real learning patterns here.
