The onboarding was terrible for the local govt. Mostly focused on legal aspects-they expected me to have office communication skills off the bat and they offered little for training with mobile techs that I was hired to do (I just did one or two projects and they assumed I already had full experience). The office politics were dreadful. Lots of meetings where things were not decided and often missing people that could answer questions. When you reach out by email, they just visit you by your desk, ask clarifying questions and explain things verbally, often referring to a site that I have to manually type in.
The large tech company had a terrific 3 month onboarding process and I was slowly eased by senior members into taking on the more repetitive work. I learned more about the company in two weeks then I did for my 6 months for that govt. If there is a question, I can reach out by email and setup an inpromptu google meet-links and commands to use are shared in the chat and easily used and tested. Decisions were made and I am building connections in the industry with people in and outside of work that do not work in my area.
As a counterpoint to your anecdote, I also just started a new job remotely at a company where they invested time and effort into their onboarding experience and it was miles better at preparing me for my role than when I onboarded at my previous two companies in person.
