The tech interview is very exam like. The interviewer asked many questions on math, Matlab, programming, controls. The math, controls, and Matlab are reasonable. I'm not very familiar with OOP and C++ though. Didn't talk about education and experience at all, just questions and answers. No feedback on the interview was provided.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
