Most students will apply through the system. You will receive an email that is generated by the database but from the student's email address with their resume and any other documents you requested in the posting. Contact the student by replying to the email or using the contact information listed in their resume.
A convenient listing of all students who have applied for your position is available by clicking the View Applicants link in the shortcuts menu on the right side of the main screen.
You may also use alternative methods such as a paper application, an application form on your website, or simply through an email by listing your preferred method in the job description field.
