First impressions count. Shake hands with your interviewers firmly, but friendly. Smile, even if you're nervous inside – it helps you to relax and makes you look more approachable. It also gives the impression that you're enthusiastic!
Be aware of your body language. Make eye contact, but don't overdo it and make sure you address everyone in the room. Avoid pointing or using gestures too much to emphasise a point, which can distract the interviewers from your answer.
Don't fold your arms; this makes you appear defensive or uninterested.
Most of our interviews are structured, with each interviewers having a number of questions to ask. Think about how you answer your questions. Don't ramble, but don't be so brief that the interviewers have to continually prompt you for more information.
Try to keep to the point and make sure you are actually answering the question.
If you do not have relevant experience of a situation, don't be afraid to say so, but suggest what you would do in that situation or think of another way to demonstrate your ability or the skills they are looking for. Equally if you don't understand a question, ask for clarification.
The interviewers may ask you questions about the information you submitted on your application form. If your last role was more senior, the interviewers may want to understand why you are applying for this role, or may ask about any gaps in your employment.
Don't forget that this is also your chance to see if the role is suitable for you. Don't be afraid to ask questions, for exampe about the role or development prospects.
