You'll see a job listed in the Applications to Review panel only if the job has candidates who are currently in the stage where you are tasked to complete reviews.
If you are a Recruiter on a job, you are responsible for reviewing candidates who are in the job's Application Review stage. If you are a Hiring Manager on a job, you are responsible for reviewing candidates who are in the job's Hiring Manager Review stage.
Note: A Recruiter will not see Hiring Manager Review tasks, and a Hiring Manager will not see Application Review tasks.
If a job does not have candidates currently in the stage where you are responsible for reviewing, the job will not appear on your My Dashboard page. Once candidates are moved into your assigned review stage, the job will appear again.
