What happens after we apply for a job?

Hello, I was wondering what happens once we apply for a job. Once we apply for a job I understand the recruiters have acces to our profile, is that right? I applied to many jobs during the last few years, but only twice got contacted by the schools (both were from South America). I have recently applied for a Spanish Teaching position in England, and I believed I am qualified for it, but I wonder if there is something wrong with my profile. I wonder if I did not write my certificates properly.

I would really appreciate your help. Thank you very much in advance,
