At work, I am working on improving new developer onboarding.

What are the most effective practices that you use or have experienced that let a new developer integrate with the team quickly and let them become productive quickly?

Also, please point me to good write-ups about great developer onboarding.

Things I have already gone through: - https://github.com/92bondstreet/awesome-onboarding - https://blog.asana.com/2013/02/onboarding-new-engineers/ - https://dev.to/codemouse92/onboarding-new-developers

Thanks!
