The term "senior-junior" often refers to a hierarchical relationship in various contexts, such as workplaces or educational institutions. A senior typically has more experience, authority, or responsibility compared to a junior. This distinction helps define roles, expectations, and mentorship opportunities within teams or groups. In many organizations, seniors guide juniors by sharing knowledge and skills, fostering professional growth. This relationship can also be seen in academic settings, where seniors may mentor juniors in their studies or projects, promoting collaboration and learning among different levels of experience.
