Applying as early as possible is recommended, mainly because you might not know how long the job posting will remain posted. If you wait, you risk the job posting period ending and missing the opportunity to apply.
Once you apply, whether you move forward in the process depends upon the the criteria for the job and how well you and other applicants match up. Other factors may also come into play, such as the number of positions being filled, the number of qualified applicants, how quickly the company needs to fill the position, etc. At this stage, applying early or later may not be a significant factor. It really depends upon the company process to review applicants.
