It was very simple interview, Questions related to, 1) C++ Virtual functions and STL. 2) Multi threading 3) CAN Even though questions are simple, Interviewers less technical skills it make me feel bad. 1) When I say I'll sync shared memory using semaphore, He was telling semaphore can't be used across process and he moved to next question. 2) Print add number in one thread and even number in second thread in consequetive manner. when I wrote code by creating semaphores like below, Interviewer said this semephore will not work and it seems he is not aware about semaphore count. sem_init(&sem_1, 0, 1); // creating semaphore with count 1 sem_init(&sem_2, 0, 0); // creating semaphore with count 0 int global = 1; thread_1() { while(1) { sem_wait(sem_1); printf("%d\n", global++ ); sem_post(sem_2); } } thread_2() { while(1) { sem_wait(sem_2); printf("%d\n", global++ ); sem_post(sem_1); } } Message to managment, Please ensure that your interviwer is technically good on the topics what he is asking during interview.
