4,347 principal engineer interview questions shared by candidates

Mostly on resume, c/c++, linux, basics of embedded OS, behavioral. All simple questions but checks your basics. Crazy thing is they want everything in one person right from assembly language, device driver, file system, DMA, OS, C/C++ and they don't stop here, they ask even cloud, databases and everything under the planet. Looks like the management have no idea what they want, what is job requirement is. They want this magician should work on anything anytime with least amount of pay
