It was wonderful! The folk at COP really know how to take care of their people.
I networked at my campus career fair, and got an invitation to an on-campus interview the next day. It was with a recruiter and a current software engineer. It was very long (1 hour) of just behavioral questions, and they had a pretty huge packet of questions and were taking notes the entire time.
A little while later, I got an invitation to fly on-site and continue interviewing. They provided travel, transportation, and stay. The night I arrived at the location, we (me and the other interviewees) were treated to a fancy dinner with recent New Hires at a local restaurant. It allowed us to ask questions and relax a little before the next day.
The actual interviews were the next morning, where we had 3 back-to-back behavioral interviews, 30-minutes each. All interviewers were friendly, personable, and transparent.
Then, we got a tour of the facility as well as the surrounding city, which ended in another nice lunch at a fancy restaurant. After that, we all flew home.
I think I waited around 2 weeks for a decision, and the recruiters were always very communicative.
Definitely a great place to interview and get experience! They treat you like a person and not a potential money-maker.
