It could potentially take up until November (or whenever the date they say in your email) to get a decision from them after your phone interview. That's why the hardest part is the wait! But it really is different for each applicant. Acceptances will come in waves, usually twice a week starting about two to three weeks after applications go live. I applied and was hired two weeks later. It was super fast for me. But for others it took much longer. Just don't stress about it!
