I was told I would hear back within 4-6 week after the f2f interview, I was not even given the group interview option. (It's like people were randomly selected.) But from what I understood, the AC rep said that everyone undergoes different processes at different stages and times. Regardless, they will contact all candidates within the time frame given. I think the chances are pretty slim for success for those who were not given the opportunity to be apart of the group. I definitely do not have high hopes.
