While interviewing for different companies and find Leetcode-like platforms to practice system design, there really isn't any good tools to practice that grill me like an interviewer. I built Scrimm.ai to solve a personal pain point: practicing System Design interviews alone is impossible and expensive (if you want to find a real person). You can read books, but you can’t simulate the pressure of an engineer poking holes in your architecture.

It’s in private beta. I’d love for you to try any of the questions and let me know if the AI is too harsh or too lenient.
