Your profile should be completed during your introduction steps when you first enter the portal. Otherwise, it should be done as soon as possible!
A quick way to fill in your profile is to create a LinkedIn profile first, filling in all information as completely as possible, and then importing your LinkedIn profile into My Profile. Your LinkedIn profile will be important for the rest of your career so crafting it now will be helpful in your job search. Note: Your system may not have the ability to associate your LinkedIn profile.
