There may be a few reasons why you don't have job matches:
1) Your application is still under review by your employer: Application review time varies by each organization.
2) Your search preferences may be too specific: In this case, try relaxing your filtering criteria. You may have turned off email and text notifications - check your account settings to ensure they are enabled.
3) There may be no jobs matching your experience and credentials: In this case, you'll be receiving job-matches as soon employers post jobs that match your credentials.
4) Employers have filled the position: In this case, you'll be receiving job-matches as soon employers post jobs new jobs that need to be filled.
