Ericsson interview questions

I received an email from school with information about the internship at Ericsson in Atlanta, GA with some questions to be filled out. I sent an email to the recruiter after answered all the questions. Then I got a call from a guy next day and confirmed all the information that I provided and schedule for an on-site interview. After a week, I went to Ericsson department to meet and talk with a manager there. I had three people interviewing me. Questions were mostly behavioral and some knowledge in Java. The questions weren't difficult and all the interviewers including the manager were really kind. After a day, I got a call from the recruiter again and told me that he received some good feedback and the offer letter will be sent through email.
