I got an email from Amazon with the above Subject line. I am confused which role is it for exactly. Can someone help me out here to identify which role it might be for. I had applied to multiple roles and looking at the amazon.jobs dashboard does not help either because it doesn't show any updates on the status. Also, in the email I got, there is no Job ID mentioned. And also what do they mean by Part 1 of 2? Does it mean there are 2 OAs?
