Followed exactly as the one said on their website, I had verbal and numerical SHLs and it should be good to practice it in advance. Then a telephone interview, questions are more about competency than technical. Something about why you want to work for them and what issues that are involved. The interviewer was quite nice to me and explained everything, however, got rejected after 2 hours with an email saying the process has finished.

It was an assessment centre that lasted about 6 hours and consisted of 4 separate interviews/tasks. The organisation was pretty much flawless, most of the staff were very nice and encouraging. It was great to receive feedback on how I did overall.
