A senior technical person called directly. I thought HR would set up the interview first, but I was wrong. He was nice and mainly focused on Linux kernel topics. You need to be dealing with the Linux kernel daily to be able to answer those questions

It is very basic, but they required the foundation, with good research in some components. It still has no more than 50 words. However, I do not know what to say; it is a common interview, like at other companies, with nothing special.

Total of 4 interviews. Interviews will be around Linux kernel knowledge and projects. Linux kernel knowledge includes: * Memory management * Block layer * File system * Spinlock * RCU * Mutex * Interrupts * Device drivers * IOMMU * DMA mapping Th
