(TN,USA) What should my wife expect to be questioned about at her naturalization interview

[AmerCan]

Wife has her naturalization interview at the end of the month at the Memphis TN field office.
Aside from the civics and english test and verifying you are you claim you are, if you have zero legal and/or civil court issues, clean record/background-check, what sort of stuff do they typically go over and ask questions about in a naturalization interview?

On average, if a person's case hasn't tossed up and red-flags when they were doing the background checks, what would the typical interview experience consist of question wise?

They simply go over information on N-400, ask question about your green card, employment, education, family, etc.

For me, we went quickly over the N-400, officer asked if anything has changed (added trip to Canada in my case) and then did the the test. Done - 15 min in total with half of it smalltalk.
