If there are a lot of candidates, companies tend to organise pre-selections or tests. For key positions or management jobs, assessment centres are often used.
Employers are looking for candidates who match the profile described as closely as possible. They expect applicants to show how their qualifications and experiences fit with this profile, talk about their professional and personal strengths and weaknesses, and answer questions about their motivation, social skills and prospects as an employee. You also have to be prepared for questions about your CV (e.g. if you have changed jobs a lot).
You can generally expect employers to be looking for a dialogue in which they can learn more about you, your qualifications and your expectations of the job. There will also be room for your questions about working hours and days, activities and job content. The atmosphere is friendly, but objective and impartial.
Candidates should be well-informed about the company: what it does or produces, its size, whether it is centralised or decentralised and whether it is based abroad, as well as about its image and philosophy.
Verbal communication is important, notably articulation and presentation in line with the job applied for (clear motivation for the job, social skills, teamwork skills, authority and leadership skills, stress resistance, flexibility). Pay attention too to non-verbal communication: punctuality, attitude, eye contact, gestures and facial expressions.
The interview usually takes about 1 hour. A video-conference may be used, but Skype is used only in exceptional circumstances and when recruiting for academic positions.
