The majority and the most obvious part of preparation is, of course, the substantive preparation for your case interview. However, you also need to present what you have learned in a way that gives your interviewer an impression of your personality and character. This means that you must appear confident and communicate clearly and precisely. The best preparation is useless if you come across as closed-off and insecure. As a consultant, you must always appear trustworthy and confident when interacting with clients to be taken seriously and to enable you and your team to work in a solution-oriented manner. This is already tested in the case interview – albeit indirectly ;) Your Body Language in the Case Interview Can Be DecisiveBody language will be a great help throughout your career to communicate clearly and build relationships. Therefore, it's time to start dealing with this topic now.A confident demeanor is advantageous in almost any profession, if not crucial. This includes a firm handshake, upright posture, and eye contact. Self-confidence signals to the interviewer that you are capable of making clear and well-thought-out decisions even under pressure.Your body language should convey openness and engagement. Avoid sitting with crossed arms and nervous gestures like drumming your fingers or playing with a pen. An open and engaged posture supports your verbal communication and shows that you are attentive and interested.💡 Prep Tip: Sit up straight and rest your elbows on the table in front of you. This creates a connection that gives you a sense of security and prevents you from making nervous movements. Clear and Precise Communication is KeyStanding out among other top talents can be challenging. The way you communicate can be a tool to achieve this. The best part is that you don't have to be "better" than the others – you will be memorable because the conversation with you was pleasant, for various reasons:Structured Problem Solving: Start by breaking down the problem and articulating your thoughts clearly and systematically. Use frameworks like the MECE principle (Mutually Exclusive, Collectively Exhaustive) to present your analysis logically and comprehensibly. Divide complex problems into manageable parts and explain your approach step by step. The trick is: think aloud.Active Listening: Show that you are actively listening to the interviewer and considering hints and questions. Ask follow-up questions if necessary to ensure you fully understand the problem. This demonstrates that you can work precisely and attentively, focusing on essential details.Clear Communication: Avoid jargon and complex expressions unless you are 100% confident in them. Your solutions should be clearly and understandably formulated. This is particularly important as consultants often have to communicate with clients from various fields. Respond to Your Interviewer with Interactive CommunicationView the interview as a dialogue, not a monologue. Interact with the interviewers by articulating your thought processes aloud and including everyone in your considerations. This can be done by asking questions like "Would it be helpful if I elaborate on this aspect?" or "What additional information might we need?"Additionally, be ready to reconsider your approaches and assumptions when new information is provided by the interviewer. This flexibility shows your ability to think dynamically and quickly adapt to changing situations.At the end of the interview, you should clearly summarize your findings and recommendations. Concisely wrap up the main points of your analysis and present your final recommendation. This shows that you can consolidate your thoughts and get to the point.Always remember: your recommendations should be realistic and feasible. Convince your interviewer that your solution is not only theoretically sound but also practically applicable. A well-founded argumentation and consideration of potential challenges are crucial here.A successful case interview in consulting requires more than just analytical skills. A convincing demeanor and clear, structured communication are equally important. Through careful preparation, confident appearance, and interactive communication, you can leave a positive impression and significantly improve your chances of a successful career in consulting. 

When applying to top consulting firms, one of the most crucial stages of the interview process is the case interview. This format is designed to assess your analytical competencies, problem-solving skills, and ability to think strategically under pressure. Let's take a look at what to expect.   Structure of a Case InterviewA case interview is a 30-minute simulation of a typical business project that consultants may have worked on. Cases provide a real example of an on-the-job experience and the assumption is that if a candidate is successfully able to tackle a case interview, he or she is also more likely to be a successful management consultant.Case studies are the most important and usually the longest part of consulting interviews. In addition to the case study, the interview typically includes introductory small talk, a personal fit interview, and closing questions (see the illustration below).Many companies review and standardize their consulting cases prior to a real interview to ensure that the case is neither too difficult nor too easy. Companies also ensure that a variety of skills are tested during the interviews. The Typical Flow of a Case InterviewThe case interview typically follows a structured flow to ensure that both the interviewer and the candidate cover all necessary aspects of the business problem. It involves the following phases:1. Case Presentation and Problem UnderstandingTo start off, the interviewer will present a specific business problem or scenario. This could range from market entry considerations, to profitability issues, or organizational changes. The problem is usually based on real-world business issues that the consulting firm dealt with in the past.You are expected to listen carefully, take notes, and clarify any points that are not clear to fully understand the scope and context of the problem.2. Framework DevelopmentAfterwards, you outline a structured approach or framework to tackle the problem. Common frameworks include the SWOT analysis, Porter’s Five Forces, or the 4P's, with which you can structure your information. This step demonstrates your ability to break down complex issues into manageable parts.However, keep in mind that it is not enough to simply memorize the standard framework concepts. While standard frameworks are useful for a rudimentary outline of a case problem, they need to be optimized and adapted to the individual case. Don't worry, as this is a skill you can develop, but it definitely requires thorough preparation and practice. Once you have crafted your structure, clearly explain your framework to the interviewer, ensuring he or she understands your thought process and logical flow.3. Analysis and Problem SolvingNext, you dive into the analysis. During the interview, your interviewer may provide additional data, charts or exhibits. Analyze this information to support your framework and build your argument. Formulate hypotheses based on your analysis and test them against the data provided. If needed, adjust your approach based on your new findings.During the quantitative analysis, perform the necessary calculations to support your findings. This could include market sizing estimations, profitability calculations or a cost analysis. Good mental math skills will definitely help in this phase.
