SWEPath: Technical Interview

SWEPath helps you prepare for technical interview questions across coding, system design, and AI engineering, not behavioral rounds. Practice with role-based roadmaps and a spaced repetition system built to make what you learn stick.

SWEPath brings interview preparation into one place. Learn, practice and retain instead of jumping between scattered resources.

- 485 technical topics across 21 engineering and AI categories
- 24,250 quiz questions (50 per topic)
- 11 role-based roadmaps
- FSRS-powered spaced repetition
- Daily Challenge and streaks

FOLLOW A ROLE-BASED ROADMAP

Choose a path for Backend, Full Stack, Frontend, Systems/Infrastructure, Data, Machine Learning, MLOps/AI Platform, AI Engineering, DevOps/SRE/Platform or System Design.

Each roadmap breaks preparation into ordered stages so you know what to study next. Prefer to explore on your own? Browse all topics by category without a roadmap.

LEARN, PRACTICE AND RETAIN

SWEPath uses FSRS (Free Spaced Repetition Scheduler) to turn quiz performance into a personalized review cycle. Strong topics are scheduled further out while weaker topics return sooner. Questions you miss can also resurface more frequently.

The goal is more than answering a question today: build knowledge you can recall when an interview arrives.

BUILD A DAILY HABIT

Take a 5-question quiz on any topic whenever you want. The Daily Challenge gives you one question each day, based on your active roadmap when you have one. Quizzes contribute to your review schedule and study streak.

A home screen widget surfaces your next recommended topic, with optional reminders.

PRIVATE AND ACCESSIBLE

No account or sign-in is required. Most learning data, including review history, streaks, settings and unlock status, stays on your device. Analytics can be disabled in Settings.

Accessibility includes adjustable text, line spacing, OpenDyslexic, high contrast and reduced motion.

FREE ACCESS AND PREMIUM

Every topic's overview is always readable. A short rewarded ad can unlock full topic content, including key concepts, and quiz access for 30 days. Premium is a one-time purchase that removes ads and unlocks all topics and quiz attempts without waiting.

Build stronger software engineering knowledge, practice technical interview questions, and keep what you learn fresh, from algorithms and databases to system design, LLMs, RAG and AI agents.
