TurbineTech: Compress and Expand: case interview walkthrough

What this case tests

This case primarily tests your ability to analyze operational processes and identify areas for improvement. You will need to demonstrate strong quantitative skills, particularly in handling data and making assumptions. The case will also assess your problem-solving approach and your ability to communicate findings effectively.

How to solve

To tackle this case, follow a structured approach:

• Begin by clarifying the problem statement and objectives.
• Gather relevant data and identify key metrics that impact operations.
• Analyze the current operational processes to pinpoint inefficiencies.
• Develop a hypothesis based on your analysis and outline potential solutions.
• Validate your assumptions with quantitative checks and logical reasoning.
• Present your findings clearly, focusing on actionable recommendations.

Quant checks to run

Quantitative analysis is crucial in this case. Consider running the following checks:

• Calculate the current operational capacity and identify bottlenecks.
• Assess the cost implications of proposed changes.
• Estimate the potential impact on revenue from operational improvements.
• Use sensitivity analysis to understand how changes affect outcomes.
• Validate assumptions with industry benchmarks and historical data.

Common mistakes

Candidates often make several common mistakes:

• Failing to clarify the problem statement adequately.
• Overlooking key data points that influence decisions.
• Making assumptions without sufficient evidence.
• Neglecting to validate findings with quantitative analysis.
• Presenting solutions without considering implementation challenges.

Practice drills

To prepare effectively, consider these practice drills:

• Review similar case studies in the industrial sector.
• Conduct mock interviews focusing on quantitative problem-solving.
• Create a list of key metrics relevant to operational efficiency.
• Practice presenting your findings concisely and clearly.
• Engage with peers to discuss different approaches to similar cases.
• Analyze past case interviews to identify successful strategies.
