Clicking on the job (from the job list) that you are interested in will take you to the job details page. After you review the job details, you can click on Apply Now button towards the end of the job detail. This will let you apply for the job on the site. As an alternative, the employer may have given a separate URL link of their own site where you want you to apply. In that case, clicking on that link will take you to the employer site to apply for the job.
