No kidding? I know at least one extremely large company which has its headquarters in that city, and I have recently been hearing good things about the modernity of their IT infrastructure.
Yep, I worked at the company you're probably speaking about for 9 years (I say probably, because there are two...Walmart and JB Hunt). I just left Walmart 3 months ago, largely because I was ready for something new, and the place I work now is just a lot more cool. Big change for me, going from giant IT building to a company that has 25 people total. They had less than 20 when I applied and 9 people a year ago.
Well, I've never heard anything about JB Hunt's IT, for good or ill, so...
That must be a weird change, yeah, but it sounds good on the whole. It's a shame the timing didn't work out on this; if I still lived in Memphis, I'd have jumped at the opportunity. (I didn't like living in Memphis very well -- Bentonville seems like it'd be much more congenial.)
I personally like Bentonville pretty well. People from larger cities often complain "there's not enough to do" but I'm a bit of a home-body myself, so that doesn't bother me. One nice thing about this area is you can get a house with 5 acres of land for between $100k and $200k that would be comparable to houses easily twice or three times as much in someplace like Seattle.
I know a little bit about JB Hunt's IT. They use COBOL and Java. They might have some other stuff, but they seem big on those two from what I've heard.
