I'm also a system programmer developer for the most part(kernel, hardware bring-up, low level firmware, performance tuning of embedded systems) and I got invited a couple times for FAANG interviews,and all of them had this system design interview with nosql column databases and loadbalancers behind nginx proxies of some sort. Problem is that, it's pretty far from my field. Are you going to ask a cloud architect who connects frontend to backend with databases at scale a lot of questions about how to write a pci express network driver in linux kernel with great performance too? I would like to be hired by a specialized hiring team in those big companies instead of going through the general hiring process that you're expected to be a technical God who knows everything at expert level. I rejected all those interview requests.
