I applied online. The process took 2 months. I interviewed at UBS (Zürich)
Interview
After accepting your CV, you'll be invited for a video interview in which you'll be asked 7-9 questions. First part was more of "basic" questions like why UBS? Second part was more specific about the banking industry. Depending on the position, you'll have to do numerical/mathematical tests or held presentations infront of seniors.
Interview questions [1]
Question 1
What challenges do you see the banking industry face in the coming 10 years and how would you overcome them
First, you have different cognitive and cultural assessments. After this, if you get selected, you receive a link for an online automatic interview. If you pass this stage, you then finally get to the in-person interviews.
Started of with numerical test, if prepared and competent it is not a hard thing, followed by online pre-recorded interview. I did not manage to make it past this point in the process.
