The Institute of Personnel Development breaks down all interview questions into five basic categories. Credential and Experience Questions are those which provide the interviewer with details of your background. Opinion Questions are straightforward requests for your views. Finally, Behavioural Questions aim to anticipate your future actions based on your previous experiences. Personnel professionals favour Behavioural Questions as they are most likely to accurately predict a successful interviewee's performance in the role.
Preparation is key.
To put you at your ease, establish the likely format of your interview and then prepare thoroughly. Your information sources on the company could include their website, company brochures, and the latest annual report. Pay close attention to anything that gives you specific details of the actual job you're going for. Sometimes a job description is provided in advance, but failing this keep going back to the job advertisement to fully understand the role. Create a strong first impression.
