Different rounds of internship with different people in the group. Mostly very typical internship interview questions that you can search on the internet. Please google. The language used was English.
I applied through an employee referral. The process took 4 weeks. I interviewed at Julius Baer (Zürich)
Interview
Meetings with line managers, potential future colleagues and Relationship Managers.
Unstructured interview, safe from some technical questions on financial instruments.
To be hired you need to be approved by all parties, including the RMs.
Very quick response time to my application from HR. The first interview was with the interested department. I did not continue because I took another opportunity at an other company.
