Modifications:

Lower proficiency levels might all read the same posting(s) and discuss what they have understood, with questions such as what are the job responsibilities? / who should apply? / how can you apply?, etc  and then practice reading and completing a sample job application (developed by the instructor). More advanced students can explore job listings individually, then be paired to exchange information about position that interested them, and discuss or justify their qualifications for the position. This could then be combined with a job interview activity, as below.
