Swisscom Scrum Master interview questions

First they rejected my application, then after 10 days - call me for an interview. First interview was good. Relaxed. He shared that there is going to be maximum 2 rounds. Tech + HR. After it, I receive an invitation for 3 hours round with 6 people ! I was like OKAAAY, maybe thats how Swiss do...
