not too deep at all.. asked about my kids names and my ex's name and if the kids are living with their mother.
and how many times i was out of the country and how long.
Also asked how many times i was married and how many times my current wife got married. that was it.
The only thing that she was interested in proof that we are still living together. as i said tax returns, bills etc.
I can relate your concern about the previous interview you had during the AOS i had a similar experience for my AOS interview. 
This was way better experience for me but again every case is different..
Good luck with your interview i hope it would go as smooth as possible.

I posted that i got my in line for interview message on tuesday.
i tried multiple times to update the list but simply i couldn't
FYI ;).
