InterviewPrepKit is a free, ad-free project built to help people learn the concepts behind technical interviews and get genuinely interview-ready — across coding, SQL, machine learning, math, agents and LLMs, and system design.
It's organized as one structured queue instead of a pile of links: a coding rep and a reading session a day. Everything runs in your browser, and your progress stays on your device — no account, no tracking of what you practice.
How it's built
This project was built with heavy, deliberate use of Claude Code, and is coordinated and reviewed by a working big-tech software engineer who vets the questions and solutions for correctness and interview realism. AI does the drafting and scaffolding; a human owns the integrity of what you study.
How the content is sourced
Problem statements here are original summaries written for teaching; each links out to the source (for example, the original LeetCode problem) so you always have the canonical version. Solutions and explanations are written from scratch. This project isn't affiliated with LeetCode, NeetCode, or any employer.
