I interviewed at cairo in 2019 First, there was a technical exam examines your programing skills c and vhdl (they only want to know whether you know how to think or not) even if you wrote the code by flow chart it was accepted, and examines your IC design knowledge + Layout, basics of Mosfet and logic circuits Then an engineer will discuss the exam with you and do a 1-1 technical interview Then he tests your english language by few questions and then you go to hr interview.
