Very long process as stated in other reviews: 1. Written interview: about 20 questions divided in 4 sections: experience, career development, education, context. I wrote about 5 pages. 2. Psychometric tests: Thomas GIA/PPA intelligence and personality tests. It's common in some companies, you can prepare online. 3. Interviews: 3 interviews, about 1 hour each. One with a senior engineer from the group I was applying to (I think it's called continous engineering, some sort of level 3 linux support), another with the team manager, and the last one with a senior engineer from another team. The guys were super chill and relaxed, mixed questions about linux, networks, c programming, debugging, the tech stack for the position (KVM, LVM, openstack, etc.). Not a hostile interview, but I guess I wasn't up to the standard because this was as far as I got.
