InterviewOS: Software Engineer Edition
The Complete Interview Preparation System
Published by Systemdr, Inc.
Welcome
You are holding the complete InterviewOS kit for Software Engineer roles — Full-Stack, Backend, and Frontend. This isn't a random pile of LeetCode links. It's a structured system built to take you from "studying" to "offer" in 30–90 days, covering every stage of the modern software engineering interview loop: coding, system design, behavioral, and the negotiation that happens after you win.

How To Use This Kit
If you have 30 days: Start with File 11 (Study Plan) — it sequences everything else for you. Spend mornings on File 02 (coding), evenings rotating between Files 03/04/05.
If you have 90 days: Week 1–2: File 01 + File 08 (build your foundation map) Week 3–8: File 02 + File 03 in parallel, 2 problems + 1 case study every other day Week 9–10: File 04 + File 05 (behavioral fluency + full mock runs) Week 11–12: File 06, 07, 09 (positioning, negotiation, company-specific polish)
If you have an interview in 5 days: File 08 (cheat sheets) → File 13 (run 2 AI mock interviews) → File 04 (STAR answers) → sleep.
How To Run an AI Mock Interview With This Kit
This kit includes a built-in AI Mock Interview Simulator — but instead of locking it behind a separate app, we give it to you as ready-to-use prompts (File 13) that work with any AI chat assistant you already have access to. Paste the prompt, answer out loud, and get scored feedback in minutes. No extra software required.
A Note on How to Practice (Not Just Study)
Reading model answers is not the same as producing them under pressure. For every module in this kit, the highest-leverage activity is active recall out loud, on a timer — not re-reading. Use File 05's mock scripts and File 13's AI prompts to force yourself to perform, not just review.
