Has anyone ever had any success landing a job using Apple job portal?

Has anyone ever had any success landing a job using their Apple job portal system? I've heard that it's who you know that can refer for you and that the job portal is useless.

If so, could you explain how long it took to get a call back after you hit the submit button?
