NBCUniversal interview questions

The interview process was great... up until it wasn't. Applied online. After about a week, I got an email from an HR rep asking me if I'd be interested in doing a screening call with them. I agreed and a few days later the call took place. The rep was super nice, and recommended me to the hiring manager. A few days later, I received word that the hiring manager wanted to interview me. The interview seemed to be going very well, and I thought they really liked me. We had a great conversation, it flowed easily and I felt we connected, even remarked that they liked a few of my answers and my question for them. Once the interview wrapped up, I left feeling great and promptly emailed my HR rep to request to send the hiring manager a thank you note. Two weeks passed, and I didn't hear anything. Finally, the HR rep replied that they were sorry for the delay, did not send the thank you yet, and that they had moved onto other candidates in those two weeks. No feedback and no offer.
