Standard FANG multi-session interview, but for lunch I was given a boxed salad and told to eat it alone in a conference room because everyone else was going to a party.

Saddest interview experience of my life.

How would you design a hierarchical database for server configuration? It should support both simple lookups for /foo/bar/baz/key and overriding values at arbitrary, non-prefix levels like /*/bar/*/key = 42.

In an elevator control system, write a method that picks the elevator that should respond to a button press.

Teams are independent and known to disregard security in the interest of moving fast. Given that you have no authority over them, how would you persuade them to secure their services?

If you're writing an internal framework or library and release a great, new feature, how do you get teams to upgrade and adopt it? (There is no mono-repo).

I hate to put "general questions about design and technology", but that's really what it was: quasi-casual conversations about resume, culture, and technology without any specific questions as such. 30 seconds on "how do you think aspect-oriented frameworks are implemented?", another 30 seconds on "what do you think of Spring Boot?", two minutes talking about a point on the resume, etc.
