Internship at Charles Schwab

Posting on behalf of a friend who has a summer intern offer in CS intern academy at Charles schwab, Austin. Got couple of questions : 0. How's the work like? Are interns given challenging tasks? 1. She will graduate before starting the internship. Ideal scenario will be a full time offer soon after the internship. Is that possible or they expect you to go back to school for at least a semester before offering a full time role? 2. What's the usual likelihood of getting offered a full time job? Of course it'll be based on team /performance 3. Can she interview with other teams while interning? There is no tag in blind for Charles Schwab?!
