When I was unemployed over the summer this was one of my daily search methods. I found more jobs that were actually applicable to me than on LinkedIn or Indeed, although it’s worth noting that they don’t have every company on there. I’d recommend adding any companies you want them to scan (there’s a form where you can drop the link to their hiring site) so you don’t have to visit all of your preferred employers manually.

I haven’t had it only give me lower quality options, but awhile back I noticed it was always defaulting to lower quality so I installed the YouTube High Definition extension. Haven’t had an issue since.
