Which of these statements is correct regarding submission of applications?

The statement that only the last submission is valid reflects a common practice in application processes, particularly for roles in competitive fields. This approach ensures that applicants have the opportunity to present their best and most updated qualifications or information. By only considering the last submission, the reviewing authority can streamline the evaluation process and minimize confusion that might arise from multiple submissions.

This way, candidates can refine their applications based on feedback or their own assessments of how to best present their skills and experiences. This method helps maintain clarity in the application process, as reviewers only need to focus on the most recent and presumably most polished submission from each candidate. In environments where multiple submissions can lead to inconsistencies or outdated information being considered, limiting the review to the last submission serves to enhance the efficiency and effectiveness of the application review process.
