Tech Interview Handbook is Yangshun Tay’s curated interview prep guide, written by the author of Blind 75 from the other side of the interviewing table at Meta. It skips “do 600 LeetCode questions” and goes straight to the minimum you actually need: which questions matter, how to approach them, and everything around the algorithms that other resources skip.

Tech Interview Handbook: Grind 75 is the question list
The repo’s most-used artifact is Grind 75, the successor to Blind 75. It’s a configurable study plan: pick how many weeks you have (1 to 16), how many hours per week, which question categories to drill, and it spits out a prioritized list with linked LeetCode problems and time-boxed targets per question. Blind 75 was the “minimum viable question list”; Grind 75 makes that list adaptive to your schedule.
The questions are sorted by actual interview frequency and difficulty curve, not by LeetCode’s arbitrary ordering. Skip the LeetCode home page and start here.
The non-algorithm chapters are the differentiator
Most interview repos stop at algorithms. This one keeps going: behavioral questions by company tier, the resume review rubric used at FAANG, offer negotiation scripts (with the actual phrases that worked), and a “best practice questions” study plan that pairs each algorithm with a one-page cheatsheet. If you’ve been heads-down on LeetCode for months and never rehearsed the opening “tell me about yourself,” this is the repo that catches what you missed.
The coding interview cheatsheet alone is worth the bookmark: a one-page Do/Don’t list for the interview itself (when to ask clarifying questions, how to write the brute force out loud, when to optimize). Read it the morning of your interview.
Read on the website, not the repo
The repo’s content is mirrored to techinterviewhandbook.org, which is the better reading surface: better navigation, rendered diagrams, and the Grind 75 tool itself lives at grind75.org. Clone the repo only if you want offline access or want to contribute.
Front end content has been split into a sister site, frontendinterviewhandbook.com, by the same author. If you’re targeting a FE/FSD role, do both.
What it isn’t
No paid course upsell inside the repo’s content (the README has sponsor placements but the actual guide is clean), no algorithm visualizations, no interactive coding environment. It’s a reading guide that points to LeetCode for practice and to its own question list for structure. Pair it with a LeetCode subscription and you have the full prep loop.
Tech Interview Handbook is the pragmatic answer when you have 4 to 8 weeks before an interview and need a structured plan, not a 600-question grind. Start with Grind 75, read the cheatsheet, work the behavioral chapter last.
