Very good experience. They obviously didn't have many cases due to COVID, so only me and one other were in the waiting room before the interview.
Had appointment at 09:30, was let in 09:20. The lady called to collect my documents 10:00. She was very nice and asked for:
* My birth certificate
* My marriage license
* My police certificate
* Joint sponsor's AOS and tax return
* Sponsor's AOS
* Evidence of relationship
She also thanked me for having such a well-documented and organized case.
10:15 my name was called over the speaker to come to window 5, where a very nice, young lady conducted the interview. She askes the following questions:
* where did you meet?
* describe your wedding to me
* what does your wife do?
* what do you do?
* do you have a place to stay in the US?
* what’s your relation to the joint sponsor?
And then she said "We have everything we need, have a good day". And that was that. They kept my passport (she said then they could issue it faster), so a little scared of getting across the Sweden/Denmark border, but no passport control when I got there, so everything went fine.
