Initial phone screening was simple, and they just asked about my resume. Next there was a face to face with the engineering manager, then i met with an electronics engineer and a mechanical engineer. Then i had to do a psychological evaluation online. Once i completed all of that, i was brought in for a 'panel interview' where I gave a presentation of my work history in front of a group of engineers, managers, and HR. I was never really asked anything too hard though, and the whole process took a long time but was not stressful.
