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.

Welche Cases für Dich am interessantesten sein können hängt natürlich von Deiner persönlichen Präferenz sowie von Deinem Wissensstand ab.
