A simple interview in which they look over your take-home assessment, probe more into your code, and inquire as to why you chose to accomplish certain features in that certain way

Great contact, reasonable time to complete technical test, nice to get that out of the way with. Useless and unclear feedback with nothing to really work from. Seemed I was rejected because I didn't write convoluted explanations or gave specific answers that they looked for. Said my answers were wrong despite them being full working answers and improvements.
