Final answer:
Interdisciplinary positions may benefit from employees having more than one certificate, though this is not a universal rule and depends on the job requirements.
Step-by-step explanation:
The statement that interdisciplinary positions can be referred on 2 certificates seems to address the requirement or advantage of having a diverse educational or certification background when applying for jobs that are interdisciplinary in nature. In some cases, this can be true, particularly if the positions require expertise in more than one field. However, whether two certifications are sufficient or even necessary can vary widely depending on the specific job or field. Some interdisciplinary roles may require only one comprehensive degree or certificate that covers multiple disciplines, while others might need multiple specialized credentials.
