It is crucial to put the time in before the interview; you will have a much better chance of performing at your best and you will feel more confident. A quick look at the recruiter’s website the day before is not sufficient!
Good interviewers are trained to base their decision on more than their first impression of you. In addition to what you actually say, how you come across (your “personal impact”) is very important in giving the interviewer a sense of whether you can work well with colleagues or clients.
Re-read the job description and criteria. Think about how you meet the requirements with specific recent examples from your experiences in work, academic life or interests / activities, make sure they are relevant to the skills required and try to focus on recent examples.
You can't predict exactly what you will be asked, but you can prepare for the typical areas that will be covered. If there is anything unusual in your application the interviewer may want to ask about this (eg time gaps or lower than expected academic grades) and think about how you will answer. Don't prepare scripted answers, they will sound very unnatural.
You need to go beyond the careers pages on their website to find out about the employer’s activities and strategy. However, for smaller organisations published information will be limited or non-existent. Research relevant professional and sector websites and publications. Keep up to date with news / current affairs, particularly with regard to issues related to your chosen occupational area.
Do you really know what the job involves? Read the employer’s recruitment information, talk to people you know working in the field. For careers and job role information use:
Check travel arrangements so that you can arrive in good time. Think about what to wear; the main objective is to look smart and professional.
