Replies to: Summer Internship Length? I don't know what specific firms policies are on this sort of thing but summer internships typically last 10 weeks and I don't think they will want to bring you on if you're going to be gone for 4 of those weeks.
All internship positions are paid and range from 10-12 weeks in duration for undergraduate internships and 11 months for post-graduate internship positions. Internships are offered in Atlanta, Los Angeles, New York, & Washington DC.
