Extreme Engineering Solutions (X-ES) Associate Embedded Engineer interview questions

They asked about personal projects I was involved in.

The engineers will probe your mind to see how much you know and to try to evaluate the way you think. They intentionally ask questions that you will not know the answer to so that they can try to gauge your thought process by seeing what your first attempts would be. They will give you hints and teach you stuff throughout the problems to see where you go next.
