4,132 embedded software engineer interview questions shared by candidates

One of the key questions they asked me during the technical round was to explain the difference between `malloc()` and `calloc()`, along with how memory is allocated and initialized in each case. They also asked me to write a small code snippet using both functions and explain how it would behave in terms of memory management and output.

They asked a lot of behavioral question in between the lines and those were fine, no funny business there and the coding questions were about: 1. string manipulation 2. bit manipulatioon 3. hash tables (or the closest you can pull on c and c++) 4. bytes manipulation and memory alignment everything was in C and nothing about dinamic programing. If you really want to get an offer from a company like this, I strongly suggest to really polish your programming style, your knowledge of the language, like really master C or C++, they don't care that you understand the problem from a high level perspective, these people are trained to select a candidate that can give the right answer to the coding challenge in the right time and discuss the answer.
