I heard once that most job openings aren't advertised -- people get them because someone knows someone looking and tells them about it.
There was a time when that was true, but in the US now its illegal for a company not to advertise a job opening, or to hire someone without first taking applications and resumes. They may still hire someone based on recommendations or reputation, but in some companies their policy is so strict about following the letter of the law, they will only take blind applications through their own website - you could know the CEO of WalMart, but he can't get you a job, you have to go through the system. Of course if you can put him down as a reference, it couldn't hurt, but it won't guarantee anything.
I did find back in the 80s, there were certain markets where I couldn't even get an interview unless I knew someone who already worked for that company, or was a professional friend of the management. It was all about networking and I don't have that skill set.
