The candidates have two ways of applying for a job:
1 – From the job advertising page which means they are redirected to the application form
2 – From the jobs section within their portal through a button called “apply now”.
This button allows them to apply for the job without completing the application form. You can remove this option by unticking a box in the job details page “Allow candidates to apply to this job via the candidate portal’
When you create or edit a job, make sure to untick the following box if you wish to remove the button.
