Read the job specification thoroughly, ensuring you have a clear understanding of the role and responsibilities so you can directly relate your previous experience to it and the organisation.
Researching the company goes without saying. They want to see evidence that you have done your homework and have genuinely thought about why you want to work for them. Review the website, annual report, and check out recent news feeds from relevant trade and national press to get a feel for market position and any current challenges - and then importantly have an opinion.
Who are you going to be meeting? Look them up on LinkedIn and understand their background and experience.
Think about the type of questions you are likely to be asked. Most interviews tend to follow the same pattern and include questions designed to establish your specific skill set, motivation and team fit.
Look the part. For most companies offering post-graduate roles (who have a dress down policy at work) a suit and tie is not necessary but you should dress in smart office wear for an interview.
For men: Smart shirt (tucked in), trousers and shoes (tie, jacket / jumper optional).
For women: Smart skirt / trousers with shirt / blouse and shoes (cardigan / jacket optional).
For senior level positions a suit may be more appropriate. Pay attention to grooming and personal hygiene including men being clean shaven, clean fingernails, neatly styled hair, tattoos & piercings covered, smelling fresh.
Plan ahead. Get the location directions, your recruiter’s telephone number, have money for emergencies, and give yourself additional time to arrive.
