Prudential Software Engineer Internship interview questions

Personally I found it very disorganized. The first interview was very straightforward, it was a phone interview with a man and a woman who asked various behavioral questions, things on my resume and also some Java questions. However after that I didn't hear back from them for about 3 weeks when I emailed them to see what next steps would be because I thought I did pretty well on that first interview. I got an email back saying they were working on it and then about a week later this woman from HR kept on calling me to talk about internships at Prudential which I thought was a miscommunication thing because I had already had a first interview but when I called her back she tried to schedule me for a Super Day in Newark in 3 days which I was not ok with because I would have to travel and miss school and it was really sprung on me. I told her to please email me because she DID have my email but she kept on calling me about 5 times about interviews until we decided to have a day where I would have 3 Skype Interviews. The first interview was technical and asked about finding duplicates in an array. The second and third were behavioral. Overall I thought I did really well on them but I did not get an offer.
