What is the role of social media in the recruitment process?
Traditionally, as they were the main place to look for jobs, newspapers (local, regional and national) were used by employers to find new staff.
Nowadays, as increased use of the internet to find news has vastly reduced the readership of almost all hard copy newspapers, employers have had to evolve and change their means of attracting applicants for vacancies.
Online newspapers (such as the Belfast Telegraph / NIJobfinder) still carry large numbers of advertisements for local jobs, but increasingly they try to maximise the potential number of applicants for that job by promoting the job on social media, including:
Facebook
Instagram
X
LinkedIn (like Facebook, but more of an employer-employee networking site rather than purely social)
Snapchat
TikTok
