There are two similar pages in Martide: Assignments and Recruitments. The difference is:
Assignments: job vacancies when you need to hire a seafarer for a contract on a set date.
Recruitments: add seafarers to the database so you can hire and deploy them in the future.
Why is there a missing interview stage in an Assignment?
First, check the Pipeline's Settings to see if the interview stage has been created.
Second, create a new Assignment because Pipeline changes are not reflected in Assignments or Recruitments that have already been created.
Who are assigned Users and Watchers?
When you’ve added a seafarer candidate to an Assignment and are in its pipeline, you can assign Users and Watchers.
The person you assign a Pipeline Stage to can be one of your company's users, a client, a Manning Agent, or one of your Custom Contacts. Assigned users need to take action.
When a Stage is assigned to someone, they will get a Notification and if they need to take action, it will be added to their My Tasks page.
If someone is a Watcher they will be kept up-to-date via their Notifications but don't need to do anything.
