I had my first round interview, which consists of basic behavioral questions. Then I had a second round, it was a group interview with 4-5 other people. We were given a case and first had to come up with our own solution, then discuss and come up with the final solution as a team and present it to the interviewers (the whole process is timed).
Tips: Don't try to dominate your team members, just try to collaborate and listen well. There was a person who spoke 95% of the time during the group discussion and I'm not sure if they wanted to hire someone like that. I almost want to say that person ruined the interview experience for the entire group. But also make sure you deliver your thoughts well and that it is implemented into to a solution. They won't remember the quiet person.
