Applying for a job doesn't necessarily guarantee a response in many cases. This is mostly a case of companies getting way more applications and resumes than they can handle. Many companies handle this by storing the incoming resumes in a database and searching for potential hires when they have an open position. It of course would be nice if these companies at least sent an automatic reply indicating that they would contact you if they were interested sometime in the future, but an automatic contact doesn't mean much either and sets the expectation that if you reply enthusiastically, you'll get a reply (which is unlikely given the volume for some companies).
