How To Prepare For An Interview

Preparation starts with understanding the purpose of the interview

Most interview advice focuses on memorising answers. That sounds sensible, but it often produces candidates who sound rehearsed rather than convincing.

Employers are rarely looking for someone who has the perfect response to every possible question. Instead, they are trying to reduce risk. Every interview is essentially an attempt to answer a small number of important questions:

• Can this person do the job?
• Will they work well with other people?
• Can we trust them?
• Will they represent the organisation well?
• Are they genuinely interested in this opportunity?

Understanding those questions changes how you prepare. Instead of trying to remember fifty model answers, you begin preparing evidence. Evidence is what employers buy. Evidence is what creates confidence. Evidence is what separates a memorable interview from an average one.

Preparation starts long before the interview invitation arrives

One of the biggest misconceptions about interviews is that preparation begins once you've received an invitation. In reality, the strongest candidates have often been preparing for months or even years without realising it. Every project you complete, every challenge you overcome and every difficult customer you help becomes potential evidence that you can use later.

The problem is that most people never collect that evidence. By the time an interview arrives they remember what jobs they've had but struggle to remember the situations that demonstrated leadership, resilience, initiative or problem solving.

• A time you solved a difficult problem.
• A situation where you improved something.
• A mistake you learned from.
• A difficult customer or colleague you handled professionally.
• A time you worked under significant pressure.
• An occasion when someone relied on your judgement.

Understanding what an interviewer is really doing

Interviewers are rarely trying to catch you out. Most are trying to answer one simple question:

"Would I feel comfortable relying on this person six months from now?"

Every question they ask is another piece of evidence that helps them answer that question.

The research that actually matters

Rather than memorising company facts, understand what the organisation does, who its customers are, what challenges it faces and what success in the role looks like.

Prepare stories, not scripts

Many candidates fail because they memorise paragraphs. A stronger approach is to prepare ten or twelve stories from your career that demonstrate leadership, communication, problem solving, teamwork, resilience, customer service and adaptability.

Why confidence is usually misunderstood

Real confidence is calmness. Candidates who pause, think and provide relevant evidence often appear more capable than those who recite polished but generic answers.

Why the STAR technique is useful (and why many candidates use it badly)

STAR (Situation, Task, Action and Result) should be an invisible structure behind a natural story, not four headings you recite.

"A customer arrived frustrated because their order hadn't been delivered on time. I listened carefully, investigated the issue, arranged an alternative delivery and followed up the next day. The customer thanked us for keeping them informed."

This sounds authentic because it focuses on the experience rather than the framework.

The evidence employers remember

Interviewers remember examples, not adjectives.

"During our busiest period I managed three client projects simultaneously, introduced a daily priority system and met every deadline."

This is far stronger than simply saying "I'm organised."

Preparing for competency interviews

Build a library of experiences covering communication, teamwork, leadership, customer service, conflict, learning, decision making and working under pressure. Most examples can answer multiple questions.

When you don't have direct experience

Transferable skills matter. Hospitality, retail, volunteering, parenting, driving or community work can all demonstrate behaviours employers value.

What your body language is communicating

• Arrive early.
• Listen before answering.
• Maintain comfortable eye contact.
• Sit naturally.
• Smile when appropriate.

Handling unexpected questions

It is perfectly acceptable to pause before answering. Employers are assessing how you think, not how quickly you speak.

Discussing weaknesses

Choose a genuine development area and explain what you've done to improve. Self-awareness is usually viewed positively.

Talking about salary

Research market rates and discuss expectations professionally, showing flexibility while demonstrating that you've prepared.

Questions to ask the interviewer

• What would success look like in the first six months?
• What qualities make someone successful in this team?
• What challenges is the department currently facing?
• How do you support learning and development?

Final thoughts

The strongest interviews feel like professional conversations rather than examinations. Preparation is about understanding your own experience, organising your evidence and communicating it clearly. Employers are not looking for perfect candidates; they are looking for people they can trust to solve problems, work well with others and make a positive contribution.

FAQs

How long should I spend preparing?

For an important interview, several focused hours are usually better than last-minute cramming. Research, evidence and practice all matter.

What should I research?

Research the organisation, the role, the team if possible, recent updates and the main responsibilities described in the advert or brief.

What is the most important part of preparation?

Preparing specific examples is usually the most useful step because most interview answers need evidence.
