The first step in the interview process is to get shortlisted for interview. This may involve you sending a tailored CV and cover letter in response to an advertised position or going through an online application process. In some cases you may be headhunted or called to interview on the basis of a strong referral. Many companies now have screening interview to assess whether you possess the qualifications and general aptitude to do the job. This may be carried out over the phone or in person, usually with a recruitment agency or an in-house recruiter. The main function of the screening interview is to narrow down the number of candidates to be called for First round Interviews.
