Business Strategy: Home Delivery Solution for Retailer Chain
Kadara, a privately-held US retailer active in the Midwest with annual sales of approximately USD 3 bn, is trying to figure out a solution to last-mile home delivery. The company currently operates out of 100 brick-and-mortar stores selling primarily groceries and home essentials (e.g. paper towels, diapers, blenders). They also sell all non-perishable products offered in their stores through their website. Currently, all sales from their website are delivered via 3rd parties (e.g. FedEx, USPS), picking up products from regional distribution centers, and their minimum delivery time is next day. Kadara does not have out-of-store delivery options but they know that services such as Instacart and Postmates are being used by customers to arrange home delivery of groceries. Kadara's management believes that they are, at best, leaving money on the table due to their limited home delivery options and, at worst, at risk of being de-selected by customers as they move towards delivery options. Kadara’s future CEO, the granddaughter of the founder, has jumped on the chance to move the company into the future. To that end, she has developed a recommendation to Kadara's board to buy Dallas Drone Technologies (DDT). DDT designs, manufactures and operates small-to-midsize flying drones. Their initial models focused on aerial photography but they added goods movement capabilities about two years ago. The future CEO believes that drone delivery is key and that Kadara should buy DDT for USD 100 m to become a leader in the space. Kadara's current CEO would like your help specifically in evaluating the option to buy DDT and generally in how to think about home delivery and the future of their business.

Russell University - Fresh Attacker on the Online Education Market (McKinsey 1st round)
Russell University, located in the United Kingdom, is one of the oldest and most prestigious universities in the world. They have been educating students for more than two centuries and provide a variety of undergraduate and graduate STEM-focused courses. In an effort to increase revenues and expand their reach, the university has recently begun offering three online postgraduate qualifications. Despite the quality of teaching and effort spent in developing these courses, the response from students in terms of sign-up rates has been modest. Russel University executives believe they are acting too slowly since other prestigious universities, particularly in the US, have successfully leveraged their brand to offer short and affordable online courses to a variety of people. Russell University has hired us to determine whether they should acquire Eduline, a well-established platform that offers STEM-related short courses to its subscribers. The university intends to use Eduline to offer courses on a subscription basis and will then issue online certificates to individuals who successfully complete its courses.

Consulting interviews are among the most competitive and difficult job interviews that exist. Interviewers use cases as an indicator to test whether you have what it takes to become a successful consultant. In order to pass, you need to ace the case interview part. And in order to ace the case interview part, you need to be well-prepared. Thus, practicing cases is one of the most important aspects of interview preparation in consulting. During different rounds of interviews you will have to solve cases again and again to prove your structured and analytical thinking as well as your communication skills.
You can practice cases on your own and go through them to get a first feeling for the structure. Afterwards, you should go into a real interview environment and practice cases with other members on the platform. You will find more than 50 mock-interview requests on the Meeting Board every day, which you can easily accept. If there is nothing suitable on the Meeting Board, you can also use the Candidate Listing. Here you can find active members on the platform and send them a direct meeting request. If you want to take your case practice to the next level, we recommend you to schedule coaching sessions with our coaches who have many years of experience in helping candidates receive their dream job offer.
In an interviewer-led case interview, the interviewer leads through the conversation. This means that the interviewer asks specific questions and also controls the time you have to analyze and answer different questions and therefore the depth of your analysis. In contrast, the candidate-led style (which is more common) is about you taking the initiative as a candidate. The initial problem is given to you by your interviewer. Afterwards, you have the freedom to structure the case according to your ideas and to ask questions proactively in order to find a solution to the problem.
Real cases in the PrepLounge Case Library are cases that were submitted by management consultancies and have been treated as such within the company. They were made available from the real interview process. In this way, you can gain deep insights into the requirements of the case interview with the respective top consultancies (e.g. Bain & Company, Roland Berger, Deloitte, Oliver Wyman). We have marked these cases with the corresponding company logo.
Expert cases were created by our PrepLounge coaches and either contain real problems that the experts have already dealt with in their lives as consultants or cases from actual consulting interviews they took part in. They offer you an optimal preparation through the different subjects, levels of difficulty and styles. And the best thing is: If you have questions about the cases, you can ask them directly to the authors.
Video case solutions are cases in which we provide you with a solution that includes a YouTube video. With this we want to help you to understand case solutions even better.
Every member has the possibility to rate a case and leave feedback on the case. This gives you the opportunity to call up a ranking and solve the cases that are particularly popular in the community. It also gives us the opportunity to continuously improve our cases in order to provide you with the best possible practice material.
Which cases are most interesting for you depends on your personal preference and your level of knowledge. If you are just starting with the case interview preparation, beginner cases are probably the most interesting ones for you. You also have the possibility to filter by different categories, such as personal fit, market analysis or brain teaser and many more, in order to address exactly the topics that are most relevant for your application.
