H1b stamping appointment for first time

[e1llab]

I have my h1b stamping appointment this week and this is the first time I’ll be doing it. I got an interview waiver even though this is my first stamping appointment, I wanted to check if anyone also got an interview waiver for the first time and how the process was. Did they ask for any additional documentation apart from the ones which are marked as required on the appointment confirmation? Any information will help, thanks!
