Example scenarios:

• "Tell me about a time when you had to make an important decision without all the information you needed. What was the outcome?"
• "Describe a situation where you had to prioritize your tasks when everything seemed urgent. How did you structure your day and manage stakeholder expectations?"

Collaborative Case & Group Dynamics

The final loop often includes a group exercise where you work alongside other candidates to solve a business-oriented case study. This is designed to simulate how you would collaborate within a cross-functional team at Nestlé.

Be ready to go over:

• Active Listening – Showing respect for other candidates' ideas and building constructively upon their suggestions.
