📝 Assessments

BCG Online Case (Casey Chatbot) chatbot case

Fit / Behavioral Interview

BCG's fit portion probes for collaborative mindset, creative thinking, and entrepreneurial drive. Stories should demonstrate you can challenge the status quo respectfully while working effectively with diverse teams.

  • Show how you challenged conventional thinking respectfully
  • Demonstrate ownership and initiative in your stories
