I talked to the recruiter of Cummins in the career fair at the university. A few days later I received an email to schedule a phone behavior interview. I talked to a engineer through phone. Three weeks later I received another email to schedule a phone functional interview. This time I talked to a site leader. I was told that the result would come out within two weeks, but four weeks passed and I hadn't been informed. So I wrote an email to follow up, and then received the offer few days later. The recruiters I've talked to are nice and made me feel comfortable during the interviews.
