From the Tools tab, select Reports, then click the radio button for the report you want. Check whether to pull the data just from your set of jobs, or from all jobs from your company. Then click Report on All Jobs to display aggregate data, or Report on a Single Job to display data for just one job. If you run a report on a single job, you'll be asked to choose the job you want to report on.

If you are viewing a job or a list of candidates for a job, you can run a report by clicking the Reports link at the top of the page.
