Cockroach Labs has developed a comprehensive onboarding process called Welcome Docs to help new employees acclimate to their roles and the company culture effectively. These personalized documents serve as a roadmap, offering resources such as team-specific information, key Slack channels, and email groups. Additionally, new hires are paired with a "Roachmate" for guidance during their first month and are assigned starter projects tailored to their roles to aid in their integration and understanding of CockroachDB. This structured approach has resulted in a significant increase in new hires' confidence and clarity about their roles, as evidenced by increased satisfaction scores from onboarding surveys. By implementing Welcome Docs, the company has managed to streamline the onboarding process, thus reducing the workload on the People team and empowering managers to independently support their new hires.
