Deloitte Consulting BTA vs. BA positions

Hi! I am an undergraduate business major senior at a 4-year university.

I was wondering if anyone knows the differences between the interviews for Deloitte Consulting's Business Technology Analyst position and Business Analyst position. I have heard that the case interview for BTA is different than for BA, but am not sure how different they are. Also, how might a business major like myself best prepare for the BTA interview? (I worked in marketing for a major tech company and other than reading blogs/enjoying tech myself, I do not know much else about technology)

If you have any other information regarding the differences between the positions, please feel free to share.

Thank you.
