Interview completed successfully. I passed the first 6 questions so did not get asked the last 4. The written test was easy as well. Straightforward interview. It took me 15 minutes at most. The funny thing is the ceremony room was closed for the entire week. As the result, the USCIS interviewer offered me to take the oath in the office right after the interview, which I did. I got the certification maybe like 10 minutes after. Overall, very surreal experience but I am glad that it is now completed. Good luck to everyone out there still.
