Social Network Sites (SNSs) have dramatically changed the way people seek new job opportunities and how organisations adapted their strategies in attracting, hiring, and retaining candidates, as well as managing the brand image. The aim of the current study is to further the motivations and rational behind employers' advertising strategies and to attempt to determine whether today's these strategies on social media may actually have a detrimental impact on the company itself, in terms of money loss, reputation, attraction, and retention of employees. 102 employees and 35 employers were recruited online through Facebook, LinkedIn, and emails, using a snowball sampling and a mixed-method approach was used to analyse the data. Pre-employment expectations were found to be strong predictors of motivation at work, job satisfaction, organisational commitment, and turnover intention. This study provided evidence that SNSs are not only shaping the world around us but also the job market.
