(also see case study interview)
Case study questions usually fall into one of the following four categories:
- Estimation questions
- Actual or theoretical client questions
- Brain teaser questions
- Graphic interpretation questions
This type of question requires you to think on your feet and work out the solution to a problem with only your own limited knowledge. Such questions include:
- How many cars are there in England?
- How many children are born each year in Europe?
- How many mobile phones will be sold in 2020?
- How many night buses are there in London?
Actual or theoretical client questions
This type of question requires candidates to analyse an actual or possible client issue. Examples include:
- A well known business wants to develop itself online. What is your advice?
- A well known high-street cafe chain is doing badly. How do you suggest they improve?
- A company has found that its revenues are higher than ever, but the company is still operating at a loss. Why is this?
- You have been contacted by a sushi chain to help them develop a plan to enter the home delivery market in a community where another sushi chain already has a market dominant position. You are the lead consultant for this client, what do you suggest they do?
Brain teaser questions are highly analytical. They test candidates by asking them to respond to questions which do not have a right or wrong answer, or even an answer at all.
Brain Teaser Example Questions
Some example brain teaser questions include:
- Why are manhole covers round?
- If you were a song being played at a fair ground carousel, what song would you be?
- How to know if the light inside refrigerator is on or not?
- How do you test a mobile phone/laptop?
- How do you know if anything your brain is comprehending is real - could it all just be in your brain?
Graphic Interpretation Questions
This type of question requires candidates to interpret data from some kind of chart or graph. The data may be actual company data, data that has been made up or data that refers to something else entirely.
