I applied online. The process took 6 weeks. I interviewed at PwC (Zürich)
Interview
The first interview is classic with HR (motivation, experience...) then the second is a business case study interview with several Managers with a pre read document sent 4 hours before.
Interview questions [1]
Question 1
HR interview pretty straight forward and classic.
Case study interview need preparation and specific mind set. Think out of the box approach. You can come with a well constructed solution to the case, the managers will challenge you to explain them the opposite solution.
