That sounds like a pretty bumpy on-boarding, least of all the group activities, but most importantly: disparate systems that seem like a ball of mud with a bunch of rituals attached. I've had on-boarding that was basically: set up SSO creds + 2FA, login to the wiki, read all of the things, install your own damn tools. I had a PR open by the end of the day. I've been at the complete opposite end as well: no PC for the first 3 days, multiple systems with unique logins and varying password requirements, file multiple tickets in some ancient (HEAT) ticketing system for access to different things, setting up meetings with different teams just to find the code and infra that it all runs on. Some companies end up with solutions that just don't age well. Most of us struggle through it because we know on-boarding will eventually end. The group activities are probably not a good indicator of things to come, but tangled systems are.
