Working at several big tech companies in industry. I can't say my experience is fully representative but I do start to see a pattern when my experiences line up with that of all my friends. There are a _lot_ of internal tools and anecdotally many of them seem like they're designed to abstract away things which wouldn't need abstracting for a company that exclusively hired high performing engineers.

Plenty of things are abstracted not because they need to be, but because they can be, and doing so increases efficiency, security, the ability to scale, and the ability of engineers to reason about the development.

And do the task consistently and correctly.
