By unlocking a selection process you can refresh the date as many times as you want, during the first 30 days from its publication. When you refresh the date of a selection process, it will reappear at the beginning of the job list, with the current date, thus obtaining greater visibility.
Subscription plans do not have a 30-day limit; all jobs you create while your subscription is active can be refreshed indefinitely. Learn about all the benefits of subscription plans here.
