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.

Zero Carbon Mine (McKinsey 1st & 2nd round)
Client goalOur client is an international mining company Global Mining Corp (GMC) that focuses on copper mining and is interested in the possibility of producing and selling “green copper”, which is the same product as normal copper but with a certified zero carbon footprint for its entire life cycle until sale. The client engaged your team to help determine the prospects for achieving net zero for their Chilean and Australian copper mines in the next 10 years and decide whether they should pursue this path.Description of situationThe client operates open pit copper mines mostly in remote areas of Chile and Australia. In most cases, the copper ore is blasted with explosives and turned into rubble, which is then collected by heavy bulldozers in big piles, loaded by power shovels onto haul trucks, which transport the material over several kilometers to the processing site. Mobile equipment is diesel operated and very heavy, up to 400 tons for a fully loaded haul truck. During processing, a series of mechanical operations take place to break down the rubble further before chemical processes like acidic leaching are used to produce the final product: copper cathodes. This material is then transported by trucks and rail to the nearest port where it can be shipped to its final destination, depending on the customer.

Die Vorstellungsgespräche bei Beratungsunternehmen gehören zu den umkämpftesten und anspruchsvollsten Interviews, die es gibt. Interviewer verwenden Cases als Indikator, um zu testen, ob Du das Zeug dazu hast, ein erfolgreicher Berater zu werden. Um zu bestehen, musst Du den Teil des Vorstellungsgesprächs mit Bravour meistern. Und damit das auch klappt, musst Du gut vorbereitet sein. Daher ist das Üben von Cases einer der wichtigsten Aspekte der Interview-Vorbereitung in der Beratung. In verschiedenen Gesprächsrunden wirst Du immer wieder Cases lösen müssen, um Dein strukturiertes und analytisches Denken sowie Deine Kommunikationsfähigkeiten unter Beweis zu stellen.
Du kannst die Cases selbstverständlich zuallererst alleine üben und durchgehen, um ein erstes Gefühl für den Aufbau zu erlangen. Danach solltest Du Dich allerdings in eine wirkliche Interview-Umgebung begeben und Cases mit anderen Mitgliedern auf der Plattform üben. Hierzu findest Du auf dem Meeting-Board täglich mehr als 50 Mock-Interview Anfragen, die Du ganz einfach annehmen kannst. Sollte nichts passendes auf dem Meeting-Board dabei sein, bietet sich aber auch das Kandidatenverzeichnis an. Hier kannst Du aktive Mitglieder auf der Plattform finden und ihnen eine direkte Meeting-Anfrage senden. Wenn Du Deine Case-Interview Vorbereitung auf das nächste Level bringen möchtest, empfehlen wir Dir, Coaching-Sessions mit unseren Coaches zu vereinbaren, die langjährige Erfahrung darin haben, Kandidaten zu ihrem Traumjobangebot zu verhelfen.
In einem Interviewer-led Case-Interview führt der Interviewer durch das Gespräch. Dies bedeutet, dass der Interviewer gezielt Fragen stellt und auch die Zeit steuert, die Du zur Analyse und Beantwortung verschiedener Fragen hast und damit auch die Tiefe Deiner Analyse. Im Gegensatz dazu handelt es sich bei einem Candidate-led Case-Interview darum, dass Du als Kandidat die Zügel in die Hand nimmst. Die Problemstellung wird Dir von Deinem Interviewer vorgegeben. Danach hast Du die Freiheit den Case nach Deinen Vorstellungen zu strukturieren und proaktiv Fragen zu stellen, um zu einer Lösung des Problems zu kommen.

Und das Beste ist: Wenn Du Fragen zu den Cases hast, kannst Du sie direkt an die Autoren stellen.
