GS SA Interview for IBD last Friday

On Friday I had interviews with GS for SA in IBD. I'm from a non-target and realized that while there I was with all other non-target students. I had 3 interviews with 2 people in each. For the latter half of the day I met with one particular group - they cycled in 7 people, which was a mix of junior and senior people. I had met one person in this group trough networking starting back in November.

Is anyone familiar with the GS SA recruiting process who could tell me if the first part of the day was just a screening? Any idea how long it usually takes them to get back? The last woman I met with on Friday told me that GS usually makes decisions quickly but that right now it was a Friday evening and everyone was trying to digestion the information.
