Simple process: 1) first interview with HRBP (she just want to understand your background and get if your personality matches OPKN's values) 2) second interview with your future manager/senior consultants you will work with. This is the most important thing: if HR likes you but you don't impress the manager, it's over

Chat about previous experience, a task to complete, questions about future technologies. They told me the outcome of the interview in a few days, but it was more a week or two
