## Overview

This repository is an embedded-systems learning and interview-preparation guide, not an executable application. Its user workflow is to follow a study path from programming fundamentals through hardware and real-time systems, then deepen or look up topics as needed and practice with Q&A and troubleshooting material. The README documents these study relationships; no source excerpts were provided, so the graph does not imply runtime calls or undocumented links.

Main entry points: [`README.md`](https://github.com/horsemann07/embedded-interview-preparation/blob/master/README.md) (Learning guide), [`Core Programming/C Interview Questions/00_C_Questions.md`](https://github.com/horsemann07/embedded-interview-preparation/blob/master/Core%20Programming/C%20Interview%20Questions/00_C_Questions.md) (C questions), [`Core Programming/C Interview Questions/01_C_Basic_Q&A.md`](https://github.com/horsemann07/embedded-interview-preparation/blob/master/Core%20Programming/C%20Interview%20Questions/01_C_Basic_Q%26A.md) (C fundamentals), [`Core Programming/C++ Interview Questions/c++_programming.md`](https://github.com/horsemann07/embedded-interview-preparation/blob/master/Core%20Programming/C%2B%2B%20Interview%20Questions/c%2B%2B_programming.md) (C++ topics)
