Consisted of tests and a video interview as well as general application questions acting like a cover letter. The interview lasted over a few months in which I completed all stages.
I applied online. The process took 4 weeks. I interviewed at UBS (London, England) in Nov 2021
Interview
They asked four questions with two minutes to respond for each. It was general questions about personal competencies and the news. Quite a good experience - I only wish they allowed an option to blur my face, since that was a distraction for me.
8 questions in total, 2 minutes recording time for each of them, 1 minute preparation time, you can review your interview after completion. There are two practice questions before the formal interview that also can be reviewed after recording.
