Group cases are not about being technically capable (although that plays a role). They're about how you behave in a team setting. Can you work in a team and add value to a team, or are you actually someone who disrupts the team / lowers others' ability to contribute?

• Can you take specific roles in a team (summarize, control time, organize process, …)
• Can you add value and contribute to the discussion?
• Can you make sure everyone has a voice?
• Do you listen to others and build up on what they say? Or help the group question their conclusions?
   

So the two big mistakes here are 1) to try to dominate the discussion too much… 2) or too little.

I've organized a few sessions on how to behave in group sessions. Feel free to reach out if you want a coaching session around this.

Hello,

Congratulations on making it to the final round! I recommend reaching out to HR to ask them whether they can share any details about the interview format, if you are unsure. You could also try asking people currently working at the company in your position.

Hi there,

Many of the same rules should apply.

In addition to that you need to be ready for CPI-specific cases/topics.
