It was all online During the first interview, he made sure I fit the requirements for the job and he talked about the company and talked about some projects on my resume. It lasted 30 minutes. I passed and went to the 2nd round with a different person. Which is the "technical" interview. We introduced ourselves and he asked a little about my senior design project. I was given a single technical question. I was asked to write a function that is equivalent to "malloc()". He gave me a few tips to get me through it, and while doing that, he asked little questions such as; "are local variables stored in the heap or stack","explain what the lines of code that you wrote are doing","what variable allows you to define the amount of bytes to get". It lasted 30 minutes.
