F1 Visa Interview After getting 221g White Slip from Dropbox Appointment

Hey guys! I have an upcoming F1 visa interview (for Fall 2022) in Chennai. This is after receiving the 221g white slip from the Dropbox appointment.

Has anyone else gone through the interview after getting a 221g-slip here? If so, could you share your experiences? Anything in particular that I should work on before the interview?

Would appreciate any comments, Thanks!!
