Interview
I got an interview through on-campus recruiting. The interview focused mainly on my resume and was very detailed in what I did (past experiences with work, old internships, etc). They also asked questions related to where I was from, why I chose my major, why I chose my university and stuff like that. If you know your resume and are prepared to go in depth with your experience you will do fine.
