Company: NVIDIA
Role: Software Engineer
Category: Software Engineering Fundamentals
Difficulty: medium
Interview Round: Technical Screen
Overview: Review three firmware fundamentals together: portable byte-order decoding, fixed-capacity ring-buffer invariants, and bounded call-stack behavior. Discuss alignment, concurrency between producer and consumer, overflow policy, interrupt nesting, and practical ways to measure stack risk.
