I bleieve that you can master case interviews and the whole interview process at consultancies firms only as long as you remember to have fun and enjoy the process. A case is not a structured template you can learn by heart - look at it as real life example and use your technical skills as well as your business sense to find your individual solution.
My expert sessions will include two parts:
(A) We will discuss the case from a technical point of view. What are do's and don'ts when cracking the case and where could you improve further?
(B) We test your business accumen and improve your skills further. By sharing real life examples with you, I will provide insightful information on the real life of a top-tier consultant.
