A candidate selection workflow defines the steps that a candidate must complete before being hired. Each step can have one or more statuses that indicate the progress of the candidate. For example, a step called Interview can have statuses such as Scheduled, Completed, Passed, Failed, etc. A candidate selection workflow can be customized for different job requisitions and can include steps such as screening, assessment, offer, background check, etc.
