The first step is an online form, send in your documents, cover letter, CV and documents. Than I had a phone interview with one of the product managers, it was very fair, mostly technical questions. He mentioned then that they want to invite me to the AC. Out of 15 people an unknown number of applicants was selected. The AC (one day) consisted of computer tests (numeracy, interpretation of diagrams), interview 1:1, group discussion (approx. 8 people), presentation (15 minutes presentation, 25 minutes for preparation)
