I had a very painless application for my visa as well. Courier picked the pack up, told me when I'd hear back from the embassy. After a couple of weeks, I got a package where they had sent back the original photos, etc. along with my passport with the visa! I wasn't called in to be interviewed.
Strangely enough, they didn't put a cover letter or anything saying I had gotten the visa, so I originally thought I had been declined... until I looked in the passport and there it was! They also didn't send back the binders that I filed everything in. I guess they liked them!
Hope everything goes well! I'm sure it will go through as long as you have everything they ask for. Best of luck!!
