I first had a phone interview round with the division manager. No really technical question, we just discussed some projects I have been working on in my previous work and during my PhD (in Computer Science). After a quick phone interview with HR, I was invited for a day of on-site interview. I met several division managers. It was more discussion than solving technical problems, I only had some simple algorithmic questions like how to implement a list, reverse it, sort it and so on.
