Participants are placed in a group with strangers and given a task to design a component for one of the company's vehicles within a tight 30-minute timeframe. The challenge is further intensified when they restrict certain actions, like sketching or talking, which adds stress and requires applicants to adapt their communication methods effectively. It's a test of both collaboration within the group and individual performance in an interview-like setting, making it the most difficult aspect of the process.
