An application is your submission for a job vacancy. When you click apply, you are telling the company: "I am interested in this job, please take a look at my CV."

Applying does not mean you have been hired immediately. It is the first step. The company receives your application, reviews your CV, compares your experience with their requirements, and decides whether to continue communication.

Before applying, it is best to carefully read the job description. If the conditions clearly do not suit you, it is better not to send an application. Thoughtful applications work better than applying en masse to everything.
