Final answer:
Three references are required only if a candidate is granted a second interview, not at the time of application or during the first interview.
Step-by-step explanation:
According to the job advertisement, three references are required if the candidate is granted a second interview. Therefore, the candidate does not need to submit references with the initial application or during the first interview. It is only after being selected for a second interview that the candidate needs to provide references. This is a common practice as it allows the employer to further assess the applicant's qualifications and suitability for the position after the initial interview phase.
