It still kind of works in some industries. I got my last 3 jobs, and 2 of them “weren’t hiring”, by walking into the joint and asking to talk to the boss and saying I can start in 2 weeks I juat have to give my current biss notice. In demanding industries, showing up in person makes an impression, another app on a stack of applications gets you nowhere. Lots of people apply, few can talk the talk and walk the walk or actually do the work. I the auto industry you show up and impress the foreman or manager with your knowledge and your pretty much in. I know people that work in welding and a construction that this also works for. I also have siblings that are white collar that this absolutely does nothing for. Supposeit also depends on how much of a giant corp you work for, as I never work for monolithic corporations. If I can’t meet my boss I can’t work there.
