When I was a job seeker, I loved the ability to hide a job listing that I'd reviewed already and saw I wasn't a fit for. Seeing the same job listing later always felt frustrating and a waste of time (on platforms where I couldn't hide the listing).
So please give job seekers the ability to hide job listings.
For example, on LinkedIn, I can click on the X in the top right corner. At that point, the job info font goes greyer in the left navigation pane and LinkedIn shows a message that says "We won't show you this job again.":
