For an ECE guy.! 1=Basic ,Digital ,Analog Electronics is a must. 2=8085/8086 microprocessor. 3=VHDL/VLSI I was given a design problem.How to switch from one memory to another memory if the entire space (i.e. 16KB) was full. Asked about basics of minimization algorithms, Binary Decision Diagrams, Kernighan Lin algo.

They ask for you to do a code review of some code snippets. In particular, they had a snippet with the malloc() family of functions which is really weird since using dynamic allocation on RTOS and embedded systems is frown upon. So this question was not relevant at all for the job since you'll never be using dynamic allocation in most embedded systems unless you want things to catch fire and explode. It's almost as if they didn't know what to ask for, but found that question online and though it would be suitable to use it on the interview.
