I am going through something similar right now! What ended up happening/how long until you heard back? I'm a new grad and I interviewed/shadowed 3 weeks ago now, and the education coordinator after the interview told me I should expect to hear back within a week. I gave it two weeks because of Labor Day and reached out to the HR contact, but still no answer. I'm surprised because all went well, and it is soo frustrating not hearing a thing!
