Very easy. Did a review of a personal project to show off engineering skill set. They were looking for architecture patterns and an understanding of REST endpoints. There was one phone interview, one technical in-person interview and that was it.
Interview questions [1]
Question 1
Do you have any personal projects that we can review?
Simple, fast responses. The interview truly was getting to know you as a person, not as a slip of paper. They want to know how you will mesh with the other employees not that you are the next Einstein.
