Element Mobile expands into refurbished phones (MBB 2nd round)
Our client, Element Mobile (EM), is the largest German telecommunications provider, with an impressive supply chain comprised of dozens of suppliers, six distribution centres, and hundreds of stores. EM offers a variety of products to its 20 million customers, including sim cards, broadband, phones, and accessories, through its two sales channels, e-commerce and brick-and-mortar stores. Recently, Element Mobile noticed a decline in the sale of their device bundles. These bundles include a SIM and a phone, which are paid for in 24 equal monthly instalments. Since SIM plans are typically purchased as part of a device bundle, and accessories and broadband packages are usually sold as add-ons, the decline in device bundles has a significant impact on our entire business.The CEO of Element Mobile believes that this decline is due to a combination of market and consumer preferences, including the reduced discretionary income of consumers and a longer device ownership trend for environmental reasons. The CEO believes that one potential solution to their declining demand is to invest in a phone refurbishing facility that would allow them to offer affordable used devices as part of their phone packages. Such recycling programmes involve the collection, refurbishment, technical inspection, and repackaging of devices.

Assume our client is CodeWave, a large software development firm headquartered in Silicon Valley. The company has a solid reputation in the tech industry and has been in operation for over 15 years. Codewave currently employs approximately 3,000 people and has rapidly expanded in recent years. Recently, the company has had difficulty retaining software engineers. Over the last year, the turnover rate for software engineers has risen dramatically, with CodeWave having to fill approximately 200 vacant positions. Simultaneously, the HR department has noticed a significant increase in the average time to fill roles, which now stands at 80 days (the time it takes from when the position becomes available to when a new person is employed and begins working). The CEO of CodeWave requested that we assist the Head of HR in determining the root causes of this trend and identifying ways to reverse it.

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.
