First Pre-recorded interview, same as others on this site. Second round technical interview, all of the questions already here, no exceptions. I chose embedded system, the only two questions that were a little bit unexpected: 1. How do you expand (A ∩ B) U C: answer: (A U C) ∩ (B U C) 2. Given a vector with random numbers, how would you delete all elements which are divisible by 5? my answer: A = A(mod(A, 5)~=0), but I am not sure if A(mod(A, 5) == 0) = [] will be better in terms of space complexity 3. What is the difference between RTOS and general purpose OS? my answer: size, support for priority based preemptive scheduling, support for priority inversion protocols, provision of high resolution of timer, efficient handling of aperiodic events.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
