What does screening in progress on hold mean?

"Screening in progress, on hold" means that a process of reviewing or evaluating something (e.g., a job application, a loan application, a movie script) is underway, but has been temporarily paused. The process hasn't been completed, but it's also not actively being worked on at the moment. There's likely a reason for the pause – perhaps someone involved needs more information, a deadline has been reached, or there's a backlog of other items needing attention.
