They go through applications and choose the most suitable. Often picking people who are over rather than just qualified, and before that there is a lot of lateral movement. People are more likly earmarked for the role. It is hard to get through the door. You will be sent for an intitial interview - they make you prepare a presentation that is timed. They WILL cut you off if you go over. This was via zoom. Second interview round involved me coming in having informal chat/interview over coffee and a tour and introductions.
