Greenhouse Recruiting's Time to Hire Per Job report helps your organization forecast the anticipated time it will take to hire a candidate for a role by displaying the length of time it took to hire other candidates for jobs.
To generate a Time to Hire Per Job report, click the ellipsis 
on your navigation bar and select Reports from the dropdown menu.
From the Reports page, navigate to the Share Progress with Executives section and click Time to Hire per Job.
IMP: A blank cell in the Job or Status columns means that information is the same as the cells above it. In the image below, both John Offer Letter and Ryan Glenn are hired candidates on the General Manager job.
If you need to change the Offer Date, Accepted Date, or Start Date, you can do that from the candidate's Private Tab. To change the Open Date, head over to the Job Setup->Job Info page.
Rather than clicking the Open Date near the top (which shows you when the whole job was opened), you can get much more specific and helpful information by clicking See Details next to No. of Openings. This button allows you to change the unique Open Date for each opening associated with the job, which is the real date that's used in this report.
How can this report be filtered?
The Time to Hire report can only be filtered by Job. You can also click the blue links in certain column to see the candidates and jobs associated with each field.
