This case is made to be interviewer-led. Therefore the interviewer should guide the interviewee through the interview.
The case is split into two parts.
The first part describes more qualitative problems and has more open questions that should make the interviewee think about the problem and its solution.
The second part is more about quantitative problems and calculations. Here the interviewee should try to make his own calculations and solve the questions.
The questions in the big boxes should be read out and shared with the candidate.
More questions to be added by you, interviewer!
At the end of the case, you will have the opportunity to suggest challenging questions about this case (to be asked for instance if the next interviewees solve the case very fast).
