What is a Case Interview?
A case interview is a specialized interview format used primarily by consulting firms to evaluate a candidate's ability to think critically, analyse data, and solve complex problems. During a case interview, the interviewer presents you with a business problem or scenario, and you are expected to work through it, propose solutions, and discuss your reasoning.

Market Sizing: Estimating the size of a market or the number of potential customers for a product.
Profitability Analysis: Identifying reasons for a company's declining profits and proposing solutions.
Market Entry: Evaluating whether a company should enter a new market or launch a new product.
Mergers and Acquisitions: Assessing the potential benefits and risks of a merger or acquisition.

Why are Case Interviews Used?
Case interviews simulate the type of work consultants do daily. They help interviewers assess several key skills, including:

A typical case interview follows a structured format:
1. Introduction
The interviewer presents the case scenario. This could be anything from a company facing declining profits to a new product launch. Pay close attention and take notes, as understanding the problem statement is crucial.

Before diving into solving the problem, ask clarifying questions to ensure you fully understand the scenario. This shows your attention to detail and helps you gather all necessary information.

Summarize your findings and present your recommendations. Be clear, concise, and confident. Explain why you chose your solution and how it addresses the problem. This is your chance to showcase your ability to synthesize information and make data driven decisions.

Be prepared for follow-up questions from the interviewer. They might challenge your assumptions or ask for deeper analysis on certain points. This tests your ability to defend your conclusions and think on your feet.
