Interviews remain the most popular method of assessment for recruitment, although more and more employers are using other methods as well. You are unlikely to get a job in Ireland without being interviewed as part of the selection process. However, they are a subjective form of assessment, that is, they rely on the interviewer's accurate recording and interpretation of your accounts of your behaviour. This is one of the reasons employers use objective assessment methods.
Interviews can vary widely in the numbers of people involved.
There may be one or many interviewers. Most commonly, graduate applicants will face one or two interviewers. Other questions ask you to imagine yourself in a given hypothetical situation and ask what you would do. The situations may be taken directly from the job in question or may be unrelated to the job. Interviewers will probably take notes as the interview goes along.
