I honestly have no idea. The last place I worked is pretty well-known. Not big tech, but a recognizable name to most people. I send out a lot of applications: those 25 interviews are the result of 150 applications in the last two months or so. And then I have my linkedin set to be discoverable and looking for a job. Basically just fiddle with the options under Visibility and Data Privacy in the linkedin settings and a bunch of people start reaching out to you immediately. I also think I have a nicely formatted resume, really readable.
