Group Discussions and Case Questions

Some employers, especially large companies and campus drives, put several candidates in one room and give them a topic to discuss. This is a group discussion, or GD. Others ask a short business problem, called a case question or a guesstimate. Both look at the same things: how you think, how you speak, and how you behave with other people. You do not have to be the loudest person to do well. You have to be clear, respectful and useful.

What observers watch in a group discussion

• Content. Do your points make sense and show you thought about the topic?
• Communication. Is your speech clear, and do you stay on the topic?
• Listening. Do you respond to what others say, and not just wait to talk?
• Teamwork. Do you include quiet people and help the group reach a point?
• Behaviour. Are you calm, polite and confident without being aggressive?

Notice that talking the most is not on the list. Candidates who shout and interrupt are usually marked down. Candidates who say fewer, better points, listen and summarise, often score higher.

Before you speak: take a few moments

When the topic is given, use the first minute to write two or three ideas. Think of the topic from several angles, which you can remember with this checklist: people (who is affected), money (costs and benefits), society, technology, time (short and long term) and risks. Even one point from each angle gives you material for the whole discussion.

A simple plan for the discussion

1. Start well, if you can. A good opening gives a short definition or context and one main point. “Social media is used by most young people. I think the key question is how to get its benefits while reducing the harm.” A clear start earns credit. But do not rush if you are not ready. A thoughtful second or third contribution is also fine.
2. Add one new point each time. Do not repeat what others said. Build on it: “Building on what Ravi said about schools, I'd add that ...”.
3. Use examples. A real example makes your point stronger than a general claim. Avoid made-up statistics. If you do not know a number, do not invent one.
4. Include others. If someone has been quiet, say: “We haven't heard from Meena. What do you think?”. It shows leadership.
5. Redirect gently if the group drifts. “We are talking about cost. Let's return to the main question.”
6. Summarise near the end, if no one has. Two or three sentences covering the main points the group raised.

Handling difficult situations

• A loud person dominates. Do not shout back. Wait for a gap and say: “That's a good point. Can I add something?”. Speak calmly and firmly.
• Someone interrupts you. Say politely: “Let me finish this point, and then I will hear yours.”
• You disagree. Do it respectfully: “I see your point, but I see it differently because ...”. Disagree with ideas, never with people.
• The discussion is chaos. Suggest a structure: “Maybe we can discuss advantages first, then disadvantages.”
• You are nervous. Take a breath, speak slowly and make your first point short. The first contribution is the hardest. It gets easier after that.

Topics you may get

Topics usually fall into a few groups: current affairs, social issues, business and economy, technology and abstract topics (“Is it better to be a leader or a follower?”). Read news regularly, from more than one source. Form a balanced view on a few big topics, and practise saying one point for and one point against. Stay away from rude or offensive statements on religion, politics or groups of people, and stay calm if others are strong in their views.

Case questions and guesstimates

A case question gives you a small business problem: “A local café's sales have dropped. What would you check?”. A guesstimate asks you to estimate something, such as the number of tea cups sold in your city per day. Nobody expects the exact number. They watch your structure and your reasoning.

Use this structure for a problem question.

1. Clarify. Ask two quick questions to understand: “Over what period did sales drop? Is it all products or only some?”.
2. Structure. Divide the problem into a few parts and say them: “I'd look at customers, the product, the price, and competitors.”
3. Explore. Take each part and give a reasonable idea of what you would check, in order of importance.
4. Conclude. Give a short recommendation and say what you would do first.

For an estimation, state your assumptions and do the maths aloud.

Estimate: cups of tea sold daily at street stalls in a town of
200,000 people. (Made-up numbers for practice only.)

- Assume 1 in 4 people drink tea from a stall on a given day: 50,000.
- Assume they have 2 cups on average: 100,000.
- So roughly 100,000 cups a day.
- I would adjust this if I knew the real habits of the town.

The answer is not important. The method, the stated assumptions and the readiness to adjust them are what the interviewer wants to see.

Practising on your own

• Practise with friends. Pick a topic, set a timer for ten minutes, and have someone observe and give feedback.
• Record yourself discussing a topic alone for two minutes. Check for structure and filler words.
• Read a short news article daily and write two points for, two against.
• Practise a quick structure for case questions on everyday businesses: a shop, a school, a bus service.

Your task

1. Pick a topic from the news. Write one point from each angle: people, money, society, technology, time and risks.
2. Hold a 10-minute practice discussion with two or three friends. Ask them to note who listened well and who added new points.
3. Practise a case question aloud using clarify, structure, explore and conclude.

How to check it worked

• You made at least two new points in the discussion and one summary.
• You invited a quiet person to speak, or used the polite way to join a busy group.
• Your case answer had a clear structure.
