Nice, we are going macro now. This is often overlooked, if you did a lateral industry shift, you have to get conversant in the industry lingo asap, so don't forget the jargon and concepts. Most standard industries are well documented, even though the documentation may be less than stellar (I'm personally looking for IP industry material to binge on, nevertheless, because it's IP(intellectual property), they don't publish much training/guide material). I tend to do the book thing but on subreddits of the particular sector/industry, I think that browsing topics on reddit is the fastest way to get conversant and begin to absorb knowledge, or more specific, awareness of existence of knowledge.
