When I was in school my teacher taught me to use "apply for" when talking about jobs. So I would say: "I would like to apply for the job as a nurse". However, I came across the sentence "What you must do before applying to jobs". Now I am really confused and cannot find a reliable answer to that question. There is just one explanation that says you´d use "apply to" when you are putting yourself forward as a candidate for something such as a job. The same source also uses the example of "appy for a job". Am I correct in assuming that both versions are possible and that "applying to jobs" is totally fine?
