Hour long interview on campus and a coding question to finish afterwards on my own. Received offer 2 weeks later. They asked a lot of questions about my projects, really wanted me to drill down to what I'm looking for out of an internship, my long term goals, technical proficiencies, how I deal with difficult people/situations, etc. They were extremely nice and were able to give me direct information on what potential areas I'd be working in as an intern. That said, it was pretty exhausting. Do not come in cold and unprepared!
