I applied through my university's recruitment system. A couple of days after the deadline I was invited to an on-campus interview with the chief of staffing. It was a 45 min behavioral interview. After this my recruiter passed on my resume and her interview notes to the team she recommended me for.

First round interview through campus recruiting, great experience. Very mellow, first round is with a professional recruiter then later rounds would be with other employees. Overall, I felt like it was not very difficult but was only a 1st round and a super friendly person. Know your resume, do some research about the company and you should be fine! I think fit is key, try to be friendly.
