Turn 18 years of hospital work into one number

You run the case. Read the prompt, answer questions from the notes below, and share data only when the candidate asks for it or gets stuck. Score at the end.

Case timer

00:00

Target length:

1. Read the prompt aloud

Read it slowly, then pause. Let the candidate ask questions before they structure.

Fictional and illustrative. You ran outpatient clinics at a hospital in the United Arab Emirates for 18 years. You redesigned booking, and the average wait fell from 40 minutes to 28. You want an expert role in healthcare operations. How do you say it?

2. Answers to clarifying questions

This case has no scripted clarifying answers. Answer from the prompt, and say "assume what you think is reasonable" if the prompt does not cover it.

3. A model structure

Compare the candidate's structure with this one. A different split can be just as good if it is clean and fits the problem.

Impact = the change in the measure / its starting value
- Starting wait: 40 minutes
- New wait: 28 minutes

4. The working, step by step

Each step shows how a strong candidate works it out. Share a new fact from it only when the candidate asks or is stuck, and let them do the math: the result in the dark box is what they should reach.

Step 1: Minutes saved per visit
What a strong candidate does: Old wait minus new wait.
Minutes saved per visit: 40 - 28 = 12
Step 2: The fall as a percentage
What a strong candidate does: Minutes saved over the starting wait.
Fall in waiting time (percent): (40 - 28) ÷ 40 × 100 = 30

The recommendation to listen for

At the end, say: "The CEO walks in. What is your recommendation?"

Say: "I cut clinic waiting times by 30 percent, from 40 to 28 minutes, by redesigning booking." One sentence, one number, one cause. Then explain how the same approach would help a client.

Risks a strong answer names: A claim without a starting number is hard to believe.

Next steps: Write three results like this one; Practise saying each in under 20 seconds.

Score the candidate

Score each criterion from 1 to 5. A 2 or a 4 sits between the descriptions.

This case has no exhibit. Score Exhibit reading on how the candidate used the data you gave them: did they pick out the number that matters and say what it means?

Structuring

1: No clear structure, or a memorized framework that does not fit the problem.
3: A sensible structure, but with some overlap, a gap, or no clear priority.
5: A structure built for this problem, with no overlap and no gaps, a stated hypothesis, and a clear first step.

Math

1: Frequent errors, no units, or needed heavy help to finish.
3: Right answers but slow or messy working, or one error caught late.
5: Accurate and clearly narrated, with units, a sense check, and what the number means.

Exhibit reading

1: Read the chart aloud without finding the number that matters.
3: Found the key number but gave only part of the so-what.
5: Pulled the right number quickly and said what it means for the case.

Synthesis

1: Summarized what was done, with no clear answer.
3: Gave an answer, but with weak reasons or no next step.
5: Answer first, then two or three reasons with numbers, the main risk, and next steps.

Communication

1: Hard to follow: long silences, no signposting.
3: Clear most of the time, with some rambling.
5: Calm and concise, signposted each step, and checked in with the interviewer.
