Some people think that they do not need to prepare for an interview as they do not know what they are going to be asked. This is simply not the case as there is always some sort of revision you can do before attending an interview with a potential employer. Firstly revisit your CV and cover letter. Have a read through and highlight any sections you wish to expand on and any anomalies (such as time out of work) that you may need to explain about. Test yourself on questions they may ask you about your CV and be sure to have a confident and correct answer ready.

Apart from re-reading your own CV, you should also spend time researching the company background. Try to find out who the managers are and a bit about the history of the business. You should also have an overview of the products and services that they sell as they may well ask you about these even if full training is offered.
