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. Every note explains the why, shows code you can run, and ends with the answer you'd actually say in the room.
What's inside
- 19 deep-dive notes on the topics interviewers return to again and again.
- 503 interview questions with model answers and the key points interviewers listen for.
- 219 quiz questions, many of them “what does this log?” puzzles, all verified by running the code.
- 14 coding challenges with tests that run in your browser.
Your data stays with you
There are no accounts, no tracking of your answers and no backend. 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.
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.
