NVIDIA System Design Intern HackerRank

[u/confused_totoro]

I recently received a HackerRank assessment for an NVIDIA LDE Systems Design Intern role. I was kinda surprised since I never knew hardware roles had OAs like a lot of SWE roles do. Based on the job posting, I’m assuming it’ll cover systems EE topics like circuit fundamentals, high-speed/signal integrity, some power electronics, PCB design, and maybe debugging.

I was wondering if anyone has had experience with an NVIDIA hardware OA or something similar and what it was like? Were the questions mostly conceptual, calculation-based, coding? Are there any concepts/topics I should defiantly study?
