Interview technique

Prior to the interview

Do your research. You should be able to comfortably outline what the company does and ideally what they are trying to achieve in the short term.
Know your CV. So that when asked you have actual examples to highlight your relevance to the position.
Familiarise yourself with the position description. Ensuring that you do indeed have the relevant technical experience.
Think about your long term goals and how this company and position can help you achieve them.Dress sharply.

Be confident, and if you are nervous remember that this is natural and can be easily managed.
Answer the questions succinctly, try and control the desire most people have to reinforce the same point twice.
Ensure that you clarify what you are being asked if it’s not clear to you the first time round.
Round off your answers; if your explanation requires detail ensure that you conclude by summarising the relevance of your example to the question that was asked.
Discuss your career goals and how this position can help.
Be enthusiastic and show your character.
If there is more than one interviewer ensure you address both/them evenly when answering.
Ask relevant questions about the role and the company. Remembering that the interview is also an opportunity for you to identify if the position is exactly what you want.
Take your time, this will ensure you are relaxed.
