Common Interview Question Types and How to Answer

You’re sitting in a bright meeting room, or perhaps staring at a video call screen, and the interviewer asks: “Tell me about a time you had to persuade someone to see things your way.” Your mind goes blank. You had prepared for “What are your strengths?” and “Why do you want this job?” — but this one catches you off guard. We’ve all been there, or know someone who has. The good news is that almost every question you’ll face in a graduate interview falls into a handful of recognisable categories. Once you understand those categories, you stop memorising answers and start preparing strategically. That shift makes all the difference.

Why Interviewers Ask Different Question Types

Employers aren’t trying to trip you up for sport. They use a mix of question types because no single question can reveal everything they need to know. A structured interview lets them assess three broad areas: your skills, your motivation, and your cultural fit. Large UK graduate schemes — from Deloitte’s audit and consulting intakes to the NHS’s graduate management training scheme — rely on structured interviews precisely because they produce fairer, more comparable results across hundreds of candidates.

The Purpose Behind Each Question Type

Each category of question does a specific job. Competency questions test whether you’ve actually done something relevant. Motivation questions check whether you genuinely want this role or are just applying everywhere. Technical questions verify you can handle the work. Behavioural and situational questions predict how you’ll act in future scenarios. Curveball questions test composure. When you know what a question is designed to measure, you can give the interviewer exactly what they need.

How to Recognise What They’re Really Asking

Listen for the framing. If the question starts with “Tell me about a time when…” or “Give me an example of…”, it’s competency-based. If it asks “Why us?” or “What attracts you to this sector?”, it’s about motivation and fit. If it presents a scenario — “What would you do if a client complained?” — it’s situational. Train your ear to spot these patterns and you’ll never be caught off guard again.

Competency-Based Questions: The STAR Method

This is the single most common question type in UK graduate recruitment. Employers like PwC and Unilever build entire assessment processes around competencies such as teamwork, resilience, and commercial awareness. They want evidence, not opinions.

What Competency Questions Look Like

• “Describe a time you worked in a team to achieve a goal.”
• “Tell me about a situation where you had to meet a tight deadline.”
• “Give an example of when you handled a conflict with a colleague.”

Using STAR to Structure Your Answer

STAR stands for Situation, Task, Action, Result. Here’s how it works in practice. Say you’re asked about teamwork. Situation: “During my second year, I was part of a four-person group project for a marketing module.” Task: “We had to produce a full campaign proposal in three weeks, and two members disagreed on the target audience.” Action: “I suggested we each research one audience segment and present data at our next meeting, then we voted based on evidence rather than opinion.” Result: “We delivered the proposal on time and scored 74%, our highest group mark that term.” Notice how the Action section is the longest — that’s where the interviewer learns what you did.

Common Pitfalls to Avoid

We see the same mistakes repeatedly. Being too vague (“I’m generally good at teamwork”) gives no evidence. Spending too long on the Situation and rushing the Action buries the important part. Failing to mention a Result leaves the story unfinished. And using “we” throughout hides your individual contribution — the interviewer needs to know what you specifically did.

Motivation and Fit Questions: Showing You Belong

These questions probe why you’ve chosen this employer and this role. They’re your chance to demonstrate that you’ve done your homework and that your values align with the organisation’s mission.

Researching the Company and Role

Start with the company’s own materials — annual reports, careers pages, and press releases. Then cross-reference with Glassdoor for employee insights and LinkedIn to see where recent graduates have gone. If you’re applying to a charity like Cancer Research UK, read their latest impact report and connect it to your own motivations. Generic answers like “I’ve always admired your work” won’t cut it; specific ones will.

Articulating Your Motivation Authentically

Link your personal story to their mission. Instead of “I want to work in healthcare because it’s rewarding,” try “My grandmother’s cancer treatment inspired me to pursue a career where research directly improves patient outcomes, which is why Cancer Research UK’s focus on early detection resonates with me.” Authenticity comes from specificity.

Handling ‘Why Should We Hire You?’

This is your closing argument. Summarise your strongest two or three selling points, tie them to the role’s requirements, and keep it under ninety seconds. “You need someone who can analyse data and communicate findings clearly. My dissertation involved statistical analysis of 2,000 survey responses, and I presented the results to a panel of lecturers. I’m also comfortable working in fast-paced teams, having balanced a part-time job with full-time study.”

Technical and Problem-Solving Questions: Demonstrating Your Skills

These questions assess whether you can actually do the job. They appear in assessment centres at firms like KPMG and Barclays, where candidates might face case studies, numerical reasoning tests, or coding challenges.

Approaching Case Study Interviews

Case studies present a business problem and ask you to recommend a solution. There’s rarely one right answer — the interviewer wants to see your reasoning. Start by clarifying the objective, then break the problem into smaller parts. If you’re asked how a retailer could increase profits, consider revenue streams and cost drivers separately before suggesting actions.

Tackling Technical Tests and Coding Challenges

For coding tests, practise on platforms like LeetCode or HackerRank beforehand. Read the problem carefully, outline your approach before writing code, and test your solution with edge cases. If you get stuck, explain your thinking aloud — interviewers often value a clear thought process over a perfect answer.

Showing Your Thought Process

Silence is your enemy in technical interviews. Talk through your assumptions, state what you’d need to know, and explain why you’re choosing one approach over another. Even if you don’t reach the “right” answer, a structured, transparent thought process demonstrates competence.

Behavioural and Situational Questions: Handling Hypotheticals

These two types are often confused, but they’re distinct. Behavioural questions ask about your past (“Tell me about a time you worked in a team”). Situational questions present a hypothetical (“What would you do if a colleague missed a deadline?”). The Civil Service uses situational judgement tests extensively in its recruitment process, so familiarity with both types is essential for public sector applications.

Behavioural Questions: Learning from the Past

Past behaviour is the best predictor of future behaviour — that’s the logic behind these questions. Prepare three or four versatile examples from work, study, or volunteering that you can adapt to different competency areas.

Situational Questions: Thinking on Your Feet

These test your judgement. There’s often no perfect answer, so focus on demonstrating sound reasoning. Acknowledge the competing priorities, explain what you’d do first and why, and show awareness of others’ perspectives.

Using the STAR Method for Both

STAR works for behavioural questions directly. For situational questions, adapt it slightly: describe how you’d handle the Situation, what Task needs completing, what Action you’d take, and what Result you’d expect. The structure keeps your answer focused and easy to follow.

Curveball and Stress Questions: Staying Calm Under Pressure

“If you were an animal, which would you be?” or “How many golf balls fit in a bus?” These questions seem absurd, but some UK startups and consultancies use them deliberately.

Why Employers Ask Curveballs

They want to see how you react when you don’t have a prepared answer. Do you panic, or do you engage with the question creatively? They’re testing composure and lateral thinking, not trivia knowledge.

Techniques to Stay Composed

• Pause and breathe before answering — a few seconds of silence is fine.
• Ask a clarifying question if it helps (“Would the bus have seats installed?”).
• Narrate your reasoning rather than searching for a “correct” answer.

Turning Odd Questions to Your Advantage

Use these moments to show personality and structured thinking. For the golf ball question, estimate the bus volume, estimate a golf ball’s volume, and divide. The arithmetic matters less than your method. For the animal question, pick one that reflects a genuine professional trait — “A border collie, because I’m organised and thrive when coordinating a team” — and briefly explain why.

Frequently Asked Questions

How many competency examples should I prepare?

We recommend preparing four to five versatile examples covering teamwork, leadership, problem-solving, resilience, and communication. These can be adapted to answer most competency questions you’ll encounter.

What if I don’t have relevant work experience?

University projects, part-time jobs, volunteering, and society roles all count. Employers care about the skills you demonstrated, not the prestige of the setting.

Should I memorise my answers?

Memorise the structure and key points, not a script. Rehearsed answers sound robotic, and interviewers notice. Practise aloud until the STAR framework feels natural.

How long should each answer be?

Aim for one and a half to two minutes per answer. Longer responses lose the interviewer’s attention; shorter ones lack sufficient detail.

Can I ask for a moment to think?

Absolutely. Saying “That’s a great question — may I take a moment to think?” shows professionalism, not weakness. It’s far better than rambling.

Preparing across every question type builds genuine confidence. Reflect on your experiences — the projects, jobs, and challenges that shaped you — and you’ll find you already have the raw material for authentic, compelling answers. Practice the structures we’ve covered, and you’ll walk into your next interview ready for whatever they throw at you.
