About PrepStacks

The central workspace for technical interview prep

We built PrepStacks to stop the 15-tab chaos and help students focus on what matters: coding, concepts, and landing their dream offer.

Our Mission

Preparing for software engineering roles and placements can feel like a full-time job. Between jumping across coding sites, bookmarking sheets, formatting resumes, checking ATS scores, and tracking contests, developers waste valuable hours managing tools instead of studying.

PrepStacks is designed to unify these tools into a single, optimized developer workspace. It is built by students, for students, to provide high-quality, free access to career-readiness and technical tools.
