The Essentials
These fundamentals apply to every type of interview — implement them all and you'll already be ahead of most candidates.
First impressions are formed in seconds — make yours count.
Presentation is one of the few things entirely within your control before you walk through the door. When in doubt, dress one level smarter than the company's everyday dress code. A well-groomed appearance signals professionalism and respect for the opportunity. If you're unsure of the dress code, it's always better to be slightly overdressed than underdressed.
Knowledge of the company shows effort, commitment, and genuine interest.
Interviewers notice immediately when a candidate hasn't done their homework. Research the company's background, recent news, values, and the specific role. Re-read your own CV so you can speak confidently about every item on it. Prepare answers to common questions using the STAR method (Situation, Task, Action, Result) and bring copies of your CV and any relevant documentation.
You were invited for a reason — the interviewer already likes your CV.
Remember: the hiring manager invited you because your CV impressed them. Your job in the interview is to confirm and expand on that impression in person. Don't be modest to the point of underselling your achievements. Speak confidently about what you've delivered, using specific numbers and outcomes where possible. This isn't arrogance — it's demonstrating value.
The best interviews feel like a two-way professional conversation.
A great interview isn't an interrogation — it's a mutual exploration of fit. Listen actively, take a breath before answering, and let your answers breathe naturally. Ask thoughtful questions that show you've done your research and are genuinely evaluating whether this role is right for you. This confidence and curiosity will impress far more than rehearsed, robotic answers.
Punctuality is the easiest way to start on the right foot.
Arriving late — regardless of the reason — creates an immediate negative impression that's hard to recover from. Plan your journey in advance, allow for traffic or transport delays, and aim to arrive 10 minutes early. If you're running unavoidably late, call the recruiter or interviewer as soon as you know. Never simply show up late without warning.
A little nerves is normal — here's how to keep them working for you.
Nerves are completely natural and can actually sharpen your focus. The key is channelling that energy rather than letting it overwhelm you. Breathing exercises, preparation, and positive visualisation can all help. Remember that interviewers expect some nerves and aren't trying to catch you out — they want you to do well.
Be Ready
Prepare for these question types before every interview. Knowing the category helps you structure your answer even when the specific question is unexpected.
Tip: Use the STAR method: Situation → Task → Action → Result.
Tip: Be honest and positive — never speak badly about a previous employer.
Tip: For weaknesses, pick a genuine one and explain the steps you're taking to improve.
Tip: Review the job description thoroughly and prepare specific examples for each key requirement.
The STAR method gives you a reliable framework to answer any competency question clearly and concisely. Structure every example answer like this:
Show Genuine Interest
Saying “No, I think I've covered everything” is a missed opportunity. Good questions demonstrate engagement and help you evaluate if the role is right for you.
Avoid questions about salary, holidays, or benefits at this stage — save those for after an offer.
Modern Interviews
Virtual and telephone interviews are now the norm for first-stage screening. The principles are the same — but there are a few extra things to prepare for.
Check your camera, microphone, and internet connection at least 30 minutes before. Have a backup plan if something fails.
Use a plain, tidy background or a professional virtual background. Avoid busy rooms, beds, or distracting posters.
Eye contact on video means looking at the camera lens, not the screen. Place the window close to your camera to make this natural.
Close other browser tabs, silence notifications, tell anyone nearby you're in an interview, and put your phone on silent.
Dress as you would for an in-person interview. It affects how you present AND how you feel about yourself.
One advantage of video interviews: you can have bullet-point notes just off camera. Keep them brief so you don't read from them.
