Round 1 - Case Study 

A case study in an Optum interview typically revolves around solving a real-world problem related to healthcare, data analysis, technology, or business strategy, given Optum’s focus on healthcare services and technology solutions. Here are some tips on how to approach a case study interview at Optum and a sample example:

Steps to Approach an Optum Case Study:

1. Understand the Problem Statement:

Take time to read the case study carefully and make sure you understand the key issue or question.

Identify the stakeholders involved (patients, healthcare providers, insurance companies, etc.) and the objective (cost reduction, improving patient outcomes, increasing efficiency, etc.).



2. Clarify Assumptions:

If there are any ambiguous elements, ask questions to clarify the problem.

You can also state your assumptions if you're making any, but be clear that these are assumptions.



3. Break Down the Problem:

Identify key data points you would need to analyze.

Break the problem into smaller pieces that can be addressed step-by-step.



4. Analyze:

Use frameworks like SWOT analysis, PESTLE analysis, or Porter’s Five Forces if applicable to the case.

In case of a data-related problem, try to identify key metrics (such as patient satisfaction, cost, quality of care, etc.) and how they can be improved or measured.

For technology-related cases, consider aspects like scalability, security, user experience, and integration with existing systems.



5. Propose a Solution:

Present your findings logically and suggest a solution based on your analysis.

Make sure to consider both short-term and long-term impacts on patient
