Visa Inc. Software Engineer(Internship) interview questions

I first applied via University, stating that I wanted to be a backend engineer. Got chosen to do a campus interview. The first was with an alumni working at Visa, which got me to the next stage which was a technical interview on campus, where they asked me javascript/css questions (kinda disappointing since I specifically said I wanted to do backend) which I had no practice with, and didn't receive an offer. Later, around December I received a basic phone screening from a recruiter asking if I was still interested in an internship. I got scheduled into a 30 minute phone interview with my soon to be manager where I just went over past experiences/classes/resume.
