Essential Homework
Find out as much as you can about the job, analyse the job description, try and work out what sort of person is required and match that to your own strengths and skills.
If you are going through an employment agency such as Kelly Services then your consultant will be able to give you a detailed job description and make sure you know all about the position before you get there.
Research the company; find out all you can about them to show you are really interested in joining. Local reference libraries can often help here or you can contact the company direct and ask for information such as the Report and Accounts and other literature. Again, if you are using an agency then you will be given relevant information.
Plan your route, giving yourself plenty of time to get to the appointment - ideally you should aim to arrive 5-10 minutes early to give yourself a chance to look around and to relax.
Think carefully about what to wear - the importance of first impressions cannot be overstated. Make sure that you look smart and professional.
Think about what it is you want to achieve from the interview. Remember it is as much for you to find out about them as the other way round. Try rehearsing with a friend giving you the opportunity to go over key points.
Make a note of any questions to ask on the day or any points you would like to cover at the interview.
