I was able to land an on campus interview after a career fair, which was pretty laid back.

I was asked all behavioral/situational questions, stuff like when is a time you solved a problem, worked through conflict, went above and beyond for your work etc.

Then I was invited to a 2 day hiring event, once again most of my interviews were behavioral based and pretty laid back, be sure you know your resume, they will ask about the specifics of your projects and such that you list.

Other than that, no real technical questions, they are really looking for eager and friendly people who are willing to learn.

Tell me about yourself.

Why do you want this position?

Describe a time you solved a conflict.

When have you had a project go wrong and how did you fix it?
