Bloomberg Analytics & Sales interview questions

I applied online for the internship position and heard back within a week to set up a phone interview. The woman called within her time frame but seemed very uninterested and I wondered how many she had had that day alone. Her first question/command was to "walk me through your resume and why you chose bloomberg" I was flustered at first and her only follow up question was why I chose finance. After approximately 10 minutes we ended the conversation and I felt very uneasy. Nonetheless 3 weeks later I received an email for a super day. The in office super day is next week and I'm doing my very best to prepare for it since Bloomberg is my top/target company
