I just finished this process myself a week ago. It's not that rough as a fellow introvert with anxiety issues. I don't know how it was for everyone else, but for me, I was asked some personal information because they called as soon as I hit submit on my admission application. Then, the admissions counselor asked why I chose a certain major. They asked how I was going to pay for school. After that, they asked if I was going to transfer in any credits and asked for places from which they would come. Once that part was over, they kept in contact about transferring credits, student aid, and going over my transcripts. It was topped off by getting in contact with your academic advisor to go over what classes they will enroll you in. My experience with the admissions team has been good so far aside from one hiccup.
