I applied and received an email from the Director of TA at 9PM one night, asking to get on a call the next day or early next week. I replied I was free to chat the next day. We had a 45 minute phone call, that I thought went really well. He asked some good questions and I was confident in my answers given my experience. He seemed really excited about me as a candidate and said he had a few more calls early the following week but would get back to me by Tuesday of the next week. Tuesday came and went with no update. I reached out Thursday morning following up, and still haven't received a response, a few weeks later. I know they are busy, but pretty disappointed in the experience. It makes it worse that I am in the TA space so I know a rejection email is the bare minimum, especially after having an interview.
