ICT Group Embedded Software Engineer interview questions

I have started with a general interview with HR about me, my educational background. In that part they just tried to learn if i can fit available position and if i can reallocate to Eindhoven. After that they sent me 2 different test, one is about c++ and another is object oriented design. It was little hard and took almost 5 hour total. After I finished my tests, we arranged an interview with a software architect. It was a technical interview, took almost 1-2 hours. We talked about my background, current work, current project and details. After that interview, they decided to pass another step. Next interview was with operation manager. He wanted to know me by asking some questions. All of the interviews (hr+architect+manager) were so polite and people from company are really positive. I didnt feel any nervous. After that interview, they send me a test again. Test was about IQ and some kind of personality questions. And they arranged me a cultural assessment meeting. This meeting was with a lady from another company. We talked about my results from previous test and my reason to change country and work. The process took 1-2 month despite of too many steps. They sent me job offer directly.
