Went to a career fair at my university and heard back within a month about coming in for on-campus interviews. The on-campus interviews were conducted by an engineer and an HR staff for approximately half an hour. The on-campus interview went well, so I was scheduled to come in for an on-site interview (within a month's time). There, I talked to senior-level management and mid-level planners, and was able to ask them about specific projects they were working on. The interview process was pretty casual and the staff I met were all very welcoming. I was asked mostly qualitative questions about relevant projects and how classes I took gave me the skills required for the position. HR was fantastic on keeping in touch and checking in with me throughout the entire process. I received prompt responses and emails whenever I had questions
