How does it differ from an entry level engineer to the head of engineering level at each of the levels, given the scope grows as well at each level?
How do each of the levels ensure they are onboarded as quickly as possible to have maximum impact ?
First, I highly recommend going through our masterclass on succeeding in a new environment. A lot of it is targeted towards software engineers, but I would say most of it applies to everyone, namely the materials around building relationships and asking questions.
For my initial comment, I'll just go through my high-level take on this: The more senior and closer to people-management you get, the more relationship-driven your onboarding will become. This means:
Hopefully someone who is at this level can leave a much better answer than me 😅
One way to think about it is, how many people are you influencing? An entry-level engineer might influence 1 or 2 people, but the CTO should influence the whole company.
Now, based on that, the people you talk to and the context you try to gather in onboarding should match that.
