v1 · Coding interview prep
Turn coding skills into an
adaptive mastery path.
Name the coding-interview topic you want to own — v1 covers data structures, algorithms and JS patterns. We generate an ordered curriculum, teach you plainly, then drop you into hands-on practice. Mastery scores adapt to your weak spots.
Your first module is free. To open the rest, press “Copy link to unlock” on your path — copying the link is all it takes.
Teach first
Plain-language explanations, not lecture videos. Read a concept in 2 minutes.
Practice in-browser
Real problems, starter code, hidden test cases. Run and iterate, no setup.
Adapts to you
Mastery per concept. The next module is always your weakest area. Your first module is free; copying your path's link opens the rest.
