Back to basics 2: the unwritten rules of interviews

Posted on 11 February 2026 • Career planning, Interviews and assessments

Got an interview coming up? Here’s what you need to know about dress code, body language, and tone to help you feel prepared on the day.

Dress the part without losing yourself: clothes, confidence, and first impressions

If in doubt, the general rule of thumb is that it’s better to be too smart than too casual (employers often expect interviewees to be smarter than everyday wear). Research the company’s values and look at what employees typically wear to help gauge where to pitch your interview outfit. Some organisations are formal, whilst others are more relaxed.

• Safe options: Smart trousers, shirts, blouses, skirts or dresses, smart shoes. A blazer if you have one.
• Avoid: Denim jeans, slogan t-shirts, clothes that show your underwear, flip flops and trainers.

Interviews: it’s how you say it, not just what you say

An interview is a two-way conversation to find out if the role is a good fit – for both you and the employer. Practice giving interviews using our Interview360 tool to build your confidence.

Here are a few tips to help you feel confident:

• Body language: Good posture helps convey engagement. If eye contact feels natural for you, that’s great, but looking at the interviewer’s face or towards them works just as well.
• Tone: Speak clearly and try not to rush. If you need a moment to think, just say “That’s a good question, let me consider that” – it shows thoughtfulness, not uncertainty.
• Preparation: Practice honest but professional answers to common questions like “Tell me about yourself” and “Why do you want this role?”
