    • Questions Asked: The case study was focused on a business problem related to data analytics. We were given a scenario and had to analyze the data provided to derive insights and propose solutions.

    • Your Approach: My team and I divided the tasks based on our strengths. We analyzed the data thoroughly, identified key patterns, and structured our solution logically. We also ensured that our presentation was clear and concise.

    • Outcome: We successfully passed this round and moved to the next stage.

  • Round 2 - Case-Debrief and EBI Round:

    • Questions Asked: This round involved a debrief of the case study we had solved earlier, along with an EBI (Experience, Behavior, and Insight) interview. The interviewer asked about our thought process during the case study, how we handled disagreements within the team, and our overall learnings from the competition.

    • Your Approach: I focused on being honest and reflective. I highlighted the collaborative aspects of our teamwork and how we leveraged each other’s strengths. For the EBI part, I shared relevant experiences that demonstrated my problem-solving and analytical skills.

    • Outcome: The round went well, and I received positive feedback on my teamwork and analytical abilities.

Preparation Tips:

  • Practice case studies in a team setting to simulate the competition environment.

Conclusion:

The overall experience was enriching, and the competition format made it unique. Working in a team helped me understand the importance of collaboration and communication. If I could do anything differently, I would spend more time practicing case studies under time constraints. For future candidates, I’d advise focusing on teamwork, clarity of thought, and being prepared to discuss your experiences in detail.
