If all the required courses are complete, you have your degree as far as I would be concerned. Your degree is not a piece of paper. It's having all the necessary classes done. Sound like you applied for graduation on time. Should you get an interview before receiving your diploma, I highly doubt they would ask to see your diploma right there at the interview. Should the situation arise, I would explain you have completed all the classes and are simply waiting for the diploma to arrive. They can confirm with the school if necessary.
You've graduated man. Congratulations!
