The full review
What is Tech Interview Handbook?
Tech Interview Handbook is a free, publicly readable guide to software engineering interviews, written by Yangshun Tay, described on the site as an ex-Meta Staff Engineer and the author of Blind 75. It is not a practice platform with an embedded code editor but a structured reference whose sidebar runs from resume writing through coding rounds, system design, behavioral rounds, salary negotiation and a closing Beyond the interview section.
The positioning targets engineers short on time. The homepage calls the material free curated interview preparation for busy people and says it covers the minimum you need to excel. The vendor reports more than a million engineers have used it.
How the handbook structures preparation
The homepage lays out a four-step path, and that path is the real product. Step one prepares a FAANG-ready resume, with sub-guides on creating an ATS-proof resume, writing software engineering specific content, and optimizing and testing the document. Step two, acing the interviews, is the largest block: step-by-step coding preparation, an algorithms deep dive, system design, and behavioral rounds. Step three covers negotiation strategies and how compensation works. Step four handles choosing between companies and understanding engineering levels.
Grind 75 and customizable study plans
The main interactive tool in the Tech Interview Handbook orbit is Grind 75, the author's successor to Blind 75. Its about page explains the reasoning: the older list was static, unranked and non-personalized, so Grind 75 draws on a pool of 169 ranked LeetCode questions, with the top 75 forming the new core. Learners set the hours per week they can commit, filter by difficulty and topic, then view results grouped by week, topic or difficulty. The FAQ notes that premium questions sit toward the back and that weekly ordering applies spaced repetition, so topics resurface.
Inside the algorithms study cheatsheets
The algorithms study cheatsheets are the densest asset here. Each topic page follows an identical template: a brief overview, learning resources, language-specific libraries, a time complexity cheatsheet, things to look out for during interviews, corner cases, and useful techniques paired with recommended practice questions. Coverage runs from Array, String and Hash Table through Linked list, Queue, Stack and Interval, up to Tree, Graph, Heap and Trie. Every entry carries a priority label of High, Mid or Low, so a candidate short on time can tell which topics matter most.
Rubrics, best practices and behavioral prep
Where Tech Interview Handbook separates itself from bare question lists is the material on being evaluated. The coding interview rubric distills what the author says top companies assess: communication, problem solving, technical competency and testing. Companion cheatsheets cover coding interview techniques for unfamiliar problems and coding interview best practices for behavior before, during and after a round. The behavioral track teaches the STAR answer format with a worked example, then adds behavioral interview rubrics, common questions to practice, and pages on preparing a self introduction and final questions to ask.
What it costs and how it stays free
There is no pricing page, no account and no paywall anywhere on Tech Interview Handbook. The site funds itself through sponsorship and says so openly: an Advertise with us block on the homepage cites more than 200,000 monthly page views from 40,000 to 50,000 unique software engineers, while the affiliate tracking carried by its outbound course links is not disclosed anywhere on the site. Read the third-party endorsements with that in mind, because paid platforms such as AlgoMonster, Design Gurus and interviewing.io sit alongside the free guides as recommended resources.
Who should choose Tech Interview Handbook
Tech Interview Handbook fits engineers who already know they must grind problems but want a defensible order of operations and a map of the whole funnel, from resume framing to offer negotiation. It suits self-directed candidates on a deadline, bootcamp graduates who need vocabulary for the process, and mid-level engineers meeting system design for the first time. It is less suited to anyone wanting a graded practice environment: the handbook points at LeetCode rather than hosting problems, and offers no worked solutions or mentorship, though the Grind 75 tool does keep a completed-questions count. Candidates outside software engineering will need a second resource alongside it.
Strengths
- Completely free and open source (MIT), no paywall on any core content
- Grind 75 tool generates a customizable, time-boxed question list — a genuine improvement on the old Blind 75
- Written by an ex-Meta/Google engineer; concise, opinionated, and grounded in real hiring practice
- Companion Front End Interview Handbook plus a free community portal for offers and resume review
Watch out for
- It's a guide, not a practice platform — no in-browser coding environment, test runner, or video lessons
- System design coverage is thin and largely defers to paid partner courses
- Deeper practice is pushed toward affiliate products (AlgoMonster, Design Gurus, GreatFrontEnd)
- Portal community features are relatively low-traffic and require a GitHub account
Key features
| Feature | What it does |
|---|
| Grind 75 | Generates a prioritized, customizable coding-question list based on how many weeks and hours you have to prepare. |
| Coding interview cheatsheets | Algorithm patterns, data-structure tips, and best-practice checklists for the interview itself. |
| Behavioral + resume guides | Frameworks for behavioral answers and a concrete resume guide tailored to software roles. |
| Community portal | Free offer-analysis, peer resume review, and question discussion at app.techinterviewhandbook.org. |
How Tech Interview Handbook compares
| Alternative | How it differs |
|---|
| LeetCode | The dominant practice platform; huge problem bank and a real coding environment, but Premium (~$35/mo or ~$159/yr) and less curated guidance. |
| Educative (Grokking the Coding Interview) | Structured, pattern-based text courses on a subscription (~$17-59/mo); more depth and interactivity, but paid. |
| AlgoExpert | Video-explained curated problems (~$99/yr) with a built-in workspace; more hand-holding than the free handbook, at a cost. |
Frequently asked questions
Is the Tech Interview Handbook really free?
Yes. The entire handbook is free and open source under an MIT license, and the companion portal (offer analysis, resume review) is free with a GitHub login. It earns via affiliate links to paid courses, sponsors, and the author's separate GreatFrontEnd product.
Is it enough on its own to pass a FAANG interview?
For strategy, structure, and a focused question list, yes — but it's a guide, not a practice platform. Most people pair it with hands-on practice on LeetCode or a paid course, especially for system design.
