• Be clear about what your major selling points are. If, by the end of the interview, these haven't been covered make a point of talking explicitly about these.
• Be to the point, make sure that you answer the interviewer's question (it sounds obvious but nervousness and a keenness to communicate your selling points can often lead you away from the point.)
• If you are asked to talk about a specific project it is worth explaining what the business aim and scope of the project was before you start talking about your involvement - it helps to set the scene.
• Never say something in an interview which can't be backed up by examples. If you say you are a 'leader’, 'creative' or 'enthusiastic' you will inevitably be asked for proof.
• Be positive. Don't overly criticise your current employer. Generally, every time you talk about a problem or issue you should always be looking to say what your involvement was in overcoming this issue.
• Sell yourself. Try to avoid giving cliched answers to interview questions (it is likely your interviewer has heard these responses more than you care to imagine). Use examples from your own experience, give your opinion.
