Honestly, AoC style problems are pretty disconnected from day to day software engineering for most people. But being pretty good at them is absolutely not a bad thing. I wouldn’t fret about learning git though. As a new member of a team, people would get you up to speed on the basics of their workflow, and I wouldn’t want to spend time becoming a git wizard and then end up having to use a proprietary wrapper around perforce unless you truly love saying Merkle tree.
