If you have a new hire coming in and you know they've never worked remotely before… that manager would probably pair them with someone like me, who has experience in remote. Conversely, I came in, I'd never used GitLab (the product) before… my buddy was somebody that knew Git and understood the technicalities of it, and my manager chose him because she thought there was no one better than this person to give me a deep dive, one-on-one tutorial on GitLab. Instead of me having to be like, "uh, I don't know how to use this… can anyone help me?" my onboarding buddy was like… made for this.
