The T will play the part of the employer who has posted the advertisement and the S will play the part of the person who has read the advertisement and is interested in finding out more. The T also informs the S that he/she will be recording the phone call.In the next lesson, the T and the S analyze the recorded phone call identifying points that were successful as well as areas for improvement.Adapted from: Watkins (2014: 111)[Watkins, P.
