Interview Questions

Real interview questions with worked answers, organized by topic and difficulty, so you can practice the areas you're weakest in instead of scrolling an unsorted list.

Coming soon

What to expect

  • JavaScript & TypeScript

    Closures, event loop, prototypes, and typing questions that come up in almost every frontend interview.

  • Data structures & algorithms

    The problems that repeat across interviews, with a plain-English explanation of the approach.

  • System design

    Common prompts — design a URL shortener, a rate limiter, a chat app — with the tradeoffs interviewers look for.

  • React & frontend

    Rendering behavior, hooks pitfalls, and performance questions specific to building UI.

  • SQL & databases

    Query writing, indexing, and normalization questions with sample schemas.

  • Behavioral

    Framing past work using structured formats like STAR, with example answers.
