It was a OA first, then a group interview solving a case. I remembered it was around 20 people in one interview, and formed a group of 5. After discission, each individual group come with an answer.

2 rounds of in-person interviews. First round was with 2 guys and the second was a 1 on 1. Only behavioural questions no technical. Focus more on your stories and how they relate if the job posting is vague research about the similar jobs so you know what to expect at the job.
