I think it highly depends on the company and product you’re working on. If you come into an agency as an IC to be rented out as a consultant, sure it’s easy to onboard because you’re essentially doing greenfield. Currently I work for a large org doing 100M+ of online revenue. I work on a team that builds tools for internal staff to manage orders. Our business is also somewhat seasonal. If someone onboards in February, its not uncommon for them to be unfamiliar with the seasonal parts of our codebase because they are only used 2 months of the year. Will they be contributing code and closing tickets in a few weeks? Yes, but they won’t be confident about the flow of the entire application and all the real world gotchas until working through at least one holiday cycle, if not two.
