GSA capital partners internship

hi, I'm a college sophomore. I had applied to gsa capital partners for a 2018 summer internships (I filled out the career thing on their website). A couple of days later someone from the firm reached out to me asking about the location preference. Followed by an email for an interview. The email said that someone from their london office will take a 45 minute to an hour long phone interview. I haven't taken that long phone interviews at all (the longest was a ~30-35 minute call with Group One Trading).

has anybody interviewed with them recently? what type of questions should I expect? glassdoor doesn't seem to be of much help?

thanks
