I applied online. The process took 4 weeks. I interviewed at UBS (Oxford, England) in Jan 2018
Interview
After having undertaken the UBS assessment (really hard because of the time limit i.e. the maths questions themselves were easy; the hard bit was that you had only 60 seconds to answer each one), I undertook a video interview. This comprised about 10 questions (1 minute thinking time for each one, then 2 minutes talking time) on why I had applied to the bank and fairly general stuff - a good think about the general financial issues at the time would likely place you in good stead for the interview.
