Overall, it was a very straight forward an easy experience! Everyone I spoke to was very pleasant and helpful. The only thing that was a little bit annoying was the wait between window 1 and 2 , which was about 2.5 hours! Other than that, everything went very smoothly - everything was explained to me clearly and processing of the visa to be issued itself have been very prompt, via the CEAC tracker. The actual interview itself was about 5-10 minutes
