Joined on a project and the unsupervised junior devs had branches for each developer, even if they were working on the same features. They were copying and pasting each others code into their personal branches to stay up to date.
Spaghetti commits took a while to unwind.
Git was just released while I was in college, and I was in a group project that required us to use SVN. First job was a TFS shop. When git finally matured to the point that it couldn't be ignored anymore, life became much much more sane.
