AT&T Sales Support interview questions

Applied for an internal job, had a phone interview which seem (in my opinion) to go very well. Hiring manager seemed to be selling the job to me instead of the other way around. Hiring manager was supposedly in a hurry to hire multiple people. I promptly followed up with a thank you email, sent a follow up email the following week letter them know I was still very interested. Didn't receive any response back. Job was reposted and no one has been hired as far as I know. Something weird going on.
