Had the interview today and oath ceremony 1hr later at the Los Angeles processing center in downtown LA. Was taken in 30mins after the interview time, and it was around 30mins long. I had two long trips (5 months and 3 months) back to back with 6 days in the US in-between (3/3 years ago), which worried me. However, the officer didn't ask anything about it. He did ask a lot of questions around why we kept moving places, mostly during pandemic to get out of the city. Civic questions were easy, just basics around term lengths etc.
All in all, it was a very smooth experience. Good luck to everyone else.
