A quick walkthrough of the tools, curriculum, and study materials inside Hexorexa.
Hexorexa is an interactive learning platform purpose-built for embedded systems engineers preparing for interviews at top-tier companies like Apple, NVIDIA, Google, Qualcomm, and Texas Instruments.
Unlike generic coding platforms that focus on web development and algorithms, Hexorexa provides domain-specific tools — RTOS simulators, hardware configurators, firmware code review practice — that mirror the actual skills tested in embedded systems interviews.

"It all started when I was preparing for my interviews at Google and Qualcomm in the embedded domain. I realized there was no single platform built for embedded engineers. I went through those interviews, learned what they actually test, and built Hexorexa from that real experience to be the one-stop solution for embedded SWE interview prep." — Aditya Pahariya, Creator of Hexorexa
When I was preparing for my Google and Qualcomm interviews, I spent weeks gathering resources — scattered YouTube playlists, random PDF notes, and outdated blog posts. Companies like Google, Qualcomm, Apple, and NVIDIA test you on RTOS internals, bare-metal C, DMA configuration, and Linux kernel drivers — but every prep resource is built for web developers.
Having gone through these interviews myself, I know exactly what gets asked. Hexorexa is the one-stop solution I wished existed. No more hunting across 20 different sources.
Hexorexa isn't just a collection of notes — it's an interactive toolbox. Every tool is designed to simulate the kind of thinking tested in real interviews: debugging race conditions, understanding scheduler behaviour, and working with hardware at the register level.
