How to prepare for summer internship applications going into a Master's Program?

I am starting a Master's Program in Data Science from a well-known university. My undergraduate degree was in Finance, so I currently do not have much background in coding or other technical skills that I assume would be asked during an interview.


I was wondering how I should prepare for summer internship applications given this situation and if anyone else went into a Master's program coming from a different undergraduate background.
