Two technical rounds back to back.

First round: Only asked about brief introduction of my skills and projects done. ARM knowledge, debugging skills about gdb, JTAG, etc. Asked two coding questions.

Round two: Very inexperienced interviewee who just sat there to reject. He asked many C basic questions and a programming question

ARM modes, how to debug in case of any fault in ARM.

He was asked to write a program to convert 24 hours into seconds and then he modified the input argument with 12 hour + AM, PM.

Determine the sizeof structure struct _data{ int i; char c; unsigned int ui; unsigned char uc; int j; };

Second Round: He was asked basic C concepts like const, volatile, use of volatile, use of const volatile,

Find the output of int main() { main() return 0 }

Find Balanced Brackets in an expression (string).

What's the problem with below function, assume compiler will not throw error and it's compilable void func(int len) { int arr[len] }
