A candidate interested in a job vacancy can apply to the employer directly by sending an e-mail or making a phone call.
The recruiter will decide whether to interview you based on the extent to which your CV matches their requirements. A covering letter is important for highly skilled posts (doctors, engineers) and should be no more than two pages long. For jobs that require a low level of qualification/education, a letter is not so important.
Employers may organise more than one interview, in which case they commonly conduct the first interview by phone. In phone interviews, the recruiter verifies that the information on the CV is authentic and asks for more detailed information about the candidate's skills, abilities and professional experience. A phone interview lasts approximately 10-15 minutes.
