The atmosphere is formal but friendly. The candidate should be attentive, responsive and positive about their application. He/she should try to relax and answer the questions confidently and as fully as possible.
The employer will be looking for examples that demonstrate the applicant's competencies to do the job. Punctuality, presentation and motivation are also important factors.
Usually only one round of interviews is carried out, sometimes with an accompanying test to gauge the applicant's technical abilities and problem-solving skills. The interview is usually 30-40 minutes maximum. Tests are 20-30 minutes. The applicant's presentation, posture and attentiveness may not be scored, but they will create an impression and are therefore important.
Because the emphasis is on competence and matching the job profile there is very little, if any, discussion on non-professional subjects. The motivation should be clear from the application form or from answers given to the interviewers' questions. You do not have to give details of your interests outside work unless you are using these as examples of your ability to do a task in reply to one of the questions.
Common questions include asking the candidate to give examples of when he/she has been in a particular situation and how he/she dealt with it. You may be asked to give examples of a time when something has gone wrong and what you did to put it right or to describe your weaknesses. In this case, show that you are aware of how to deal with your weakness.
Towards the end of the interview, you will be asked if you have any questions. Prepare one or two questions in advance, for example you may want to ask about opportunities for progression within the company or what types of training the company offers.
