Keep in mind, this was in 2005, so i'm not sure if things have changed at all since then.
I interviewed with Cerner for a software dev job.
They booked me on a flight that arrived in KC about 10pm Sunday night. They picked me up and took me to the hotel.
They picked me up at 8am Monday morning and brought me to their offices.
I spent about 2 hours being interviewed by a few different people.
Then they took me straight to the airport for the return flight.
No rental car. No time to check out the area or anything.
They called me a couple days later and offered me a job.
I said no thanks.
The travel arrangements, along with the whole interview process, left me with the distinct impression that they didn't give a crap about their employees or potential employees.
I've interviewed with several other companies over the course of my career and all of them have made arrangements to provide a rental car and give me time to explore the area. One company even made arrangements to have me spend the day with a realtor, so they could give me a tour of the various areas of the city and look at some houses. It seems pretty obvious that someone who is considering relocating might want to see the area they would be relocating to. But Cerner only seemed concerned with getting me in and out as fast as possible and as cheaply as possible.
That's just my experience and it was over 8 years ago, so take it for what it's worth.
