Who can help facilitate the integration of new employees into a firm's culture?

The correct answer is mentors. Mentors play a crucial role in helping new employees navigate a firm's culture. They offer guidance, support, and insights based on their own experiences within the organization. This relationship can significantly ease the transition for new hires by providing them with a trusted point of contact who can answer questions, offer advice, and help them understand the norms and values of the workplace.

While supervisors, fellow employees, and HR specialists all contribute to the onboarding process, mentors specifically focus on personal and professional development within the context of the company culture. They facilitate social integration, which can enhance job satisfaction and engagement for new employees, leading to better retention rates and overall team cohesion.
