I was also told the same thing. I also told Atlas I would find it appropriate to give my currently employer a two week notice if I was a successful applicant. One HR lady did mention that they would be giving calls in 4-7 days after the interview to. For me, that would be cutting it close. Everyone that I know, hasn't heard a word, good or bad.
Patience and humility are the key. Go back through this thread and you'll find that the Atlas HR department is 'right-sized" which means that during a push like this they are not exactly overwhelmed but probably past max capacity and they may or may not get the invited out in a timely manner.
Also, there are dozens and dozens of Atlas applicants who have been trying to get on here for years. If you have some sort of special "in" at Atlas as some of your posts have alluded, it might be better form to keep it to yourself.
