The interview lasted 1.5 hours. It took place together with the Group Leader and HR. The questions were quite ok. They asked a lot about microprocessors, microcontrollers and C programming language. For some questions regarding the architecture on an controller or microcontroller I had to draw and explain each component.

It was good not that though and being confident is the most important thing , speaking like professional helps a lot , explain them apart from the things me mentioned in the resume and even your hobbies to in your introduction
