Thread bump.
For any that may have applied, I have been informed that the original EXTERNAL announcement was CANCELLED, causing some confusion about the application process and plans to hire.
I queried up the chain and was told that BIG HR had made a mistake on the original external announcement and had to cancel it and resubmit for another open application period. I was also told that some who had applied under the former announcement might have to resubmit under the new announcement. I don't know what might have prompted some to get an email stating to resubmit the application and others have not. Taking all of that information in, I think it would be in anyone's best interest to contact the HR POC on the announcement and CONFIRM the status of your particular application.
