My current role for the first time exposed me to amounts of data and variety of data (in type and how/where it's stored) that's difficult to learn organically.

My current role for the first time exposed me to amounts of data and variety of data (in type and how/where it's stored) that's difficult to learn organically. I wonder how a FAANG does that at "scale". > most of that information is carried by the Data engineers who have built the system, and they are over-whelmed with questions that could be answer with a good system, but derive power over analysts. Is that the kind of question you're talking about here?
