Good engineering culture?

I hope this refers to something behind the scenes that I as a Hotmail/Outlook user am unable to see. Because UI and product-wise, I don't see much evidence at all that someone of a good engineering culture cares about the experience I'm having with the product.

More like a team phoning it in.

Would likely be different teams working on spam detection and on the frontend though. The cultures could vary wildly between them, as well as how they fit into the wider product development flows/structures.
