You are likely to have already fulfilled the basic academic and experience requirements, so this is a chance for the employee to find out more about you as a person and how your experiences make you suitable for the job. Your communication skills and ability to interact will be assessed at interview, so try to relax and be yourself.
Before attending interview make sure you research the company fully. Re-read the job description, your CV and your application form. Think about the types of questions you may be asked, and how you would answer to best demonstrate your suitability for the job. Try to avoid yes/no answers to questions, but instead be detailed and draw on your past experiences.
If you are asked to attend a technical interview or give a presentation make sure that you are fully prepared. If you are unsure about the requirements, ask the employer. It is better to take this initiative than to show up to the interview unprepared. If you have a practical interview in a lab or other technical environment, make sure that you are appropriately dressed.
Interviews are also a chance for you to find out more about the company and whether it is somewhere that you would like to work. You are likely to be given the chance to ask the employers some questions: use this opportunity to find out more about the company and what your role would include, not whether the staff parties have an open bar!
If you’re attending an interview at a pharmaceutical company, you may need to pass through security on arrival so allow plenty of time to get there.
