The best way to prep - lack of material

I've recently had a networking event for a local bank, where I met people on the S&T desk. After doing a lot of research I think that S&T (more sales focused tbh) might be a better fit for me than compared to corporate finance. Although there is far less material or prep to go around for this side of banking. Any advice or material on this topic to prepare for a potential internship application? Is the interview process much different compared to corp fi? Any information helps.
