These are the main technical questions that I had encountered in the two technical interviews: - Interrupt routine life time. - Pins of the SPI and its operation. - Causes of stack overflow. - Difference between memories in terms of speed/density/usage/cost/operation. -PWM operation and parameters. -Difference between startup code / boot loader. -In which memory the Interrupt vector table lies and in which position inside the memory. -Function that takes an array and eliminates any repetitive elements inside an array and returns it (find a proper way to return it). -Function that takes an array and prints another array with same size where the elements in the new array are the number of repetitive times of its indeces .in the input array. Example : Input = [1 2 4 5 6 2 4 0 2 2 3 3] output=[1 1 3 2 1 0 1 0 0 0 0 0] Explanation: 0 was repeated 1 time in the input array so we write 1 at the 0 index at the output array. 1 was repeated 1 time in the input array so we write 1 at the 1 index at the output array. 2 was repeated 3 times in the input array so we write 3 at the 2 index at the output array. 3 was repeated 2 times in the input array so we write 2 at the 3 index at the output array. 4 was repeated 1 time in the input array so we write 1 at the 4 index at the output array. 5 was repeated 0 time in the input array so we write 0 at the 5 index at the output array. ... and so on so forth
