BofA Quant Summer Analyst Video Interview 2019. Not sure how to prepare.

Hello,

I recently applied to BofA's Quant Summer Analyst Program for 2020. I sent my resume and cover letter to one of the MDs in Atlanta and later got selected for the first round. Now I recently started a MS Finance program and my undergraduate background was not in finance. In my cover letter I talked about how I am currently taking a class that uses the software R but will not be introduced to python until the spring. A friend of mine just did the first interview and said its mostly technical questions about python. How should I approach this? Right now my knowledge of python is pretty nonexistent. I do not want to blow my chances, but at the same time I would be exposed to a lot of technical material until the spring. Also, not sure if I should post this here or in a different field forum.
