Case study interviews for graduate roles at beer companies
Graduate schemes at beer and drinks companies often use a case study round. The format is learnable. What separates candidates is whether their answer sounds like it understands how beer is made, moved and sold in India.
A case interview tests how you think, not what you know
A case study interview hands you a business problem and watches you work through it, usually in 20 to 45 minutes. The interviewer cares less about the final number than about how you broke the problem down, which assumptions you stated and whether you changed course when new information arrived.
Beer companies use cases for graduate roles in sales, marketing, supply chain, finance and analytics. Some give you the case live with a single interviewer. Others send a short pack the day before and ask for a presentation. A few run a group case at an assessment centre, where how you treat the other candidates is scored too.
None of this needs a brewing degree. It does reward a candidate who can say why a beer problem is different from a soap or biscuit problem.
The cases beer companies set fall into four families
Most cases we hear about from graduates land in one of these:
- Market sizing. How many litres of beer are sold in Pune in a year? How many draught taps are there in Bengaluru?
- Profitability. A brand's volume is flat but margin has fallen. Why?
- Launch or entry. Should the company launch a wheat beer in a new state?
- Operations. A plant cannot meet summer demand. What are the options?
Each family has a standard skeleton. Market sizing is population, then drinkers, then frequency, then volume per occasion. Profitability is revenue minus cost, then each side split until the culprit shows. Learn the skeletons, then practise until you stop sounding as if you are reading one.
Beer has quirks that change the answer
This is where you earn marks. A few facts a sharp interviewer will hope you raise:
- Excise and pricing are set state by state. A launch plan that works in one state may not work across the border, because duty, permitted pack sizes and route to market differ. Say that rules vary and you would check the current position.
- Direct alcohol advertising is restricted in India. Brand building leans on the outlet, the pack and the people who serve it.
- Demand is seasonal. Summer peaks are real. A plant sized for the average month falls short in April and May.
- Beer takes time to make. A lager can spend three to five weeks in tanks before packaging. You cannot brew your way out of a stock-out next week.
Drop one of these into the right place and the interviewer hears someone who understands the product.
A worked market sizing answer
Say the case is the annual beer volume for a city of 10 million adults. A clean answer states each step out loud:
- Assume a share of adults drink beer at all. State a round figure and say it is an assumption.
- Split drinkers into frequent and occasional.
- Give each group a number of occasions a year and a volume per occasion, for example one 650 ml bottle.
- Multiply, then sense-check the result in hectolitres (one hectolitre is 100 litres).
Finish by naming what would move the number most: the share of drinkers, the summer peak or the switch between bottles and cans. Interviewers mark the sense check heavily. A result that implies every adult drinks a crate a week should make you stop and say so.
How to prepare in two weeks
Do ten cases out loud with a friend timing you. Read two or three recent annual reports from listed drinks companies to pick up how they describe volume, price and mix. Visit three outlets and note the price of the same beer in a bar, a shop and a restaurant.
Then learn enough about the product to talk about it without bluffing: how malt becomes wort, what fermentation does and why packaging is where most of the cost and most of the losses sit. Our guide on data and analytics jobs in drinks companies shows how this knowledge gets used day to day. If the role is in planning, supply chain and procurement jobs is worth a read too.
The gap most graduates leave open
Case books teach the structure. They cannot teach you why a brewery's capacity is really set by fermenter days or why a pasteurised bottle and an unpasteurised keg need different stock plans. Graduates who can explain the process in plain words tend to stand out in the room, because few others try.
Your first step: pick one beer you can buy locally, write down every stage it went through from barley to the shelf and practise explaining it in two minutes. If you get stuck on any stage, that is the stage to learn before the interview.
Common questions
Do beer companies use case study interviews for graduates?
Many do, especially for sales, marketing, supply chain, finance and analytics schemes. Formats vary from a live case with one interviewer to a group exercise at an assessment centre.
Do I need brewing knowledge for a beer company case interview?
You do not need a brewing qualification. A plain understanding of how beer is made and sold in India helps your answer sound grounded and often sets you apart.
What kind of market sizing questions come up?
Typical questions ask for annual beer volume in a city, the number of outlets or draught taps in a market or the size of a new category such as wheat beer.
How long should I prepare?
Two focused weeks of out-loud practice with a partner, plus some outlet visits and a basic grasp of the brewing process, is a sensible minimum.
