VVDN Technologies Embedded Engineer Trainee interview questions

At first there was a writen test consist of 20 basic electronics 30 C questions and 10 embedded related question.Test was some what difficult.Then went to the interview panel contain three interviewers.They asked mainly relate to our writen exam.They cross examine our writen exam.Then analyse it and asked about the question which were not attended.Then give time to solve the unanswerd or wrongly marked questions. Test questions from basic electronics, - voltage divided rule 3 qns - Nortan equalent - 8:1 mux related - Electronic circuit with diode,zener diode,LED,transistors,capacitors,counter,Logic gate - 20 bits can address how much kilobytes - adrrs rage of 8085 for the given circute with A12-A15 from C program - pointers - structures - array - typedef union - ++i and i++ - pointer with array many qns - int const *p and int *const p(something like this) - function with in fuction from embedded, - diff b/w embd os & gen purps os - what is malloc and alloc - architecture based on instruction set - total number of addrs space for 8085(some thing like that)
