No, it may be structured or unstructured, formal or informal, by a panel or with a group.
The interviewer will discuss your CV, focusing on training and academic work as much as on work experience. They may ask about your attitudes and personality. They will want to identify what you are like, how you behave in certain situations and how you fit in to a team.
Besides a representative from the HR department, there may also be a technical professional to ask questions related to thetasks of the role. The HR representative will focus on personal and general skills and working conditions.
The candidate can then ask additional questions before the interview concludes with practical arrangements for the decision period and feedback. Make the most of the farewell to show that you are optimistic and expect good news.
Be aware that your non-verbal communication gives information about you throughout the interview to confirm or belie what you are saying. Answer questions about errors or criticism sincerely. We all make mistakes. What is important is how you learnt from the situation. Always tell the story from a positive point of view and draw positive conclusions.
If faced with uncomfortable or provocative questions, try to remain calm. Difficult questions are commonly used in the selection of senior executives, sales personnel or customer liaison staff
