Very quick HR, asking many many technical questions during the phone interview and assessment centre, which potentially demonstrates the motivation, but somehow is too focused on these technical parts. Nobody, who hasn't worked in the role before, can be that exact with all the technology-related questions and I think it is always better to focus more on skills and talent of person than purely on what one has read up online. My impression is that they are looking for a rather homogeneous group of people to make up teams, so anybody not falling for that type of category won't be successful. All employees seemed to be very very similar to each other and there was no large variety in backgrounds, cultures, beliefs, etc. So, in my opinion, either you fit in there, or otherwise they won't compromise for the diversity. They gave no feedback after the assessment centre, so it was not nice after spending time preparing for the telephone interview and assessment centre, thus getting a standard answer as when you send in only your CV.
