Onboarding is the process of integrating new employees into an organization and familiarizing them with the company culture, policies, and practices. It typically begins as soon as the new employee accepts the job offer and can last from a few days to several months, depending on the complexity of the role and the organization's onboarding program.

It's a process that helps new hires get up to speed on everything they need to know to succeed in their new job. The purpose of onboarding is to help new employees understand their role within the organization, get to know their colleagues and acquire the skills and knowledge needed to perform their job effectively. It can include orientation sessions, training, job shadowing, and introductions to key stakeholders.

Effective onboarding can have a significant impact on the success of new employees and the organization as a whole. It can help reduce turnover, increase job satisfaction, and accelerate the integration of new employees into the team.
