Tom Spiegelman, an Infrastructure Engineering Manager at DigitalOcean, has successfully implemented a Fellowship Program to foster mentorship and growth within his team. The program brings together engineers from various teams for a two-week immersive experience, where they work on projects with the Infra team and receive guidance from senior engineers. This approach has led to increased comradery between teams, improved tool development, and successful recruitment of talented engineers. By pairing individuals with more senior engineers, Spiegelman believes that strong-minded engineers can be developed internally, leading to better performing teams and a stronger company. The program's benefits include quick iteration, focused mentoring, and the ability to cater to each participant's interests. Despite challenges, such as affecting team members' busy schedules, the program has been successful in achieving its goals and has become an integral part of DigitalOcean's organizational growth.
