Interview prep material tends to fall into two camps: endless lists of questions with shallow answers, or documentation that's too long to revise from. Stacktrick sits in between. The library combines longer code walkthroughs with focused articles that explain the why, show a practical scenario and offer an interview exercise with reasoning.
Who runs it
Stacktrick is run by Aditya Mishra, a Technical Lead at BNP Paribas in Mumbai who has built Angular, React, Java and Spring Boot applications since 2016. The domain was his personal blog from 2021 to 2024; it relaunched in September 2026 as an interview-prep site focused on the stack he works in.
How it's made
The guides, model answers and cheat sheets are drafted with AI tools and published only after Aditya has chosen the topic and reviewed the result. JavaScript, TypeScript and Python examples are run before they appear; Java, Spring Boot and Angular examples are checked against the documentation for the versions each guide names. When a guide couldn't be checked properly, it isn't published: in November 2026 the library was cut back to the guides that passed that review, and more return as they are checked. The editorial policy has the details.
What's inside
- In-depth guides that explain the why behind an interview question or a common error, with a worked example and a practice question.
- Interview questions with model answers and the key points interviewers listen for, chapter by chapter: JavaScript, TypeScript, React, Angular, HTML & CSS, Node.js, Java, Spring Boot, SQL & PostgreSQL, Docker, Git & CI/CD, Data Structures & Algorithms, System Design.
- Quizzes, flashcards, a mock interview and a voice coach built from those questions.
- Coding problems and challenges with tests that run in your browser.
Your practice data stays with you
There are no accounts, and your answers aren't sent to Stacktrick. Your progress, streak, stickers, flashcard schedule and saved code live in your browser's local storage. You can export them as a file from your progress page and import them on another device. The site itself uses Google Analytics and Google AdSense, and two practice tools rely on outside services (Java code runs on Judge0, and the voice coach uses your browser's speech recognition); the privacy policy explains each.
How to use it
- Follow the 6-week roadmap or jump into any chapter.
- Read a note, then take the linked quiz while it's fresh.
- Review flashcards for five minutes a day; spaced repetition does the rest.
- Before the real thing, do a timed mock interview and a few speed rounds.
Interview tip
Practice saying answers out loud. Knowing something and explaining it clearly under pressure are different skills, and the second one is what gets you hired.
