Today's interview styles vary immensely, however from the candidate perspective, the basic principals remain the same. The interviewer may be assessing you on a number of different levels; from your ability to handle the role to your motivations for joining them: your overall professionalism and the cultural fit.

The following points may help you when preparing for the interview:

• Research the Company and, if possible, the interviewers
• Research the interview format 
• Make a good impression i.e. conservative dress, arrive early
• Be personable as well as professional
• Be aware of both verbal and non-verbal communication
• All questions will be asked for a reason, answer them accordingly
• Make notes about the interview to help with your feedback
