Need interview advice to get into GPU programming related roles

Hi everyone, I’m seeking advice on getting into a CUDA/GPU related roles. I have 2.5 years of experience at a startup working on LLM inference and LLMOps, and I’m currently pursuing OMSCS (Georgia Tech). I've an undergrad in ECE from NITW. My goal is to move into CUDA/GPU systems or performance engineering roles, ideally at NVIDIA or similar companies. I’d appreciate insights on

- which skills matter most beyond basic CUDA,
- how deep GPU architecture knowledge is expected,
- what projects best demonstrate readiness,
- finally, how do I increase my chances at getting in such roles...

Any advice from those who’ve made a similar transition or are in such roles would be greatly appreciated.
