If you've ever prepped for a software engineering interview, you know the drill. Forty browser tabs. Three half-finished Notion docs. A YouTube playlist you'll never get through. And the nagging feeling that you're studying the wrong thing.
We built Sensei because interview prep shouldn't feel like that.
What Sensei is
Sensei is a structured study companion for engineers preparing for mid, senior, and staff-level interviews. Instead of scattered blog posts, everything is organized into study cards that break a question down the way an interviewer actually thinks about it:
- The core concept, explained plainly
- How to reason through it out loud in an interview
- Tradeoffs and common mistakes that separate a good answer from a great one
- A sample answer, follow-up questions, and even how to split your time between a 2-minute and a 5-minute version
The library covers system design, backend, frontend, databases, security, testing, CI/CD, observability, API design, and behavioral questions. Over 50 deep-dive cards and 160 quiz questions at launch, with syntax-highlighted code and real diagrams throughout.
Track what you actually know
Reading something once doesn't mean you can explain it under pressure. Sensei ships with topic quizzes that explain every answer, a progress dashboard that shows where you're strong and where you're bluffing, and personal notes on every card so your own insights live next to the material.
You can save solutions, add your own questions, search everything instantly, and back up your progress as a JSON file you own. It installs as an app on your phone or desktop and works offline.
Try it
Sensei is live today at sensei.igit.space. No signup, no paywall while we're building out the library. If you're an engineer with an interview on the calendar, we'd love to hear what you think.
