The Interview process was fine. the intreviwer asked about my last position, explaind about the design of the system I worked on. some question about design of scale syste, working with HW , how to test some critical failure. asked about manage team, what tools i used to handle all priorities of tasks. asking for c++ design system, I asked to write c++ system that run 3 threads parallel and every thread print it's on charcter only, the order must be kept. example : the print will be : abcabcabc .... , another question : about memory allocation, mutex, semaphore. they were 3 questions : 1 question is to fix the code, the second one is how to improve it and the last one is to write the thread pool that print charcters. asking for c++ design system, I asked to write c++ system that run 3 threads parallel and every thread print it's on charcter only, the order must be kept. example : the print will be : abcabcabc .... , another question : about memory allocation, mutex, semaphore.
