Cap1 Internship Value

recently got a cap1 internship, why is it so highly valued as a big tech feeder and having good results post grad? Some people I've heard would take it over legitimate tech/big tech companies despite it being a bank for an internship but then wouldn't touch it with a 6 foot pole for full time new grad, so what makes it so lucrative in the eyes of a recruiter as an internship or is it just overvalued for some reason
