Many drivers drive long distances to their DC just to get in. You can transfer after 1 year.
I'm driving 120 miles one way. Other guys on some of the forums are driving well over 250 miles one way. Walmart does not expect you to relocate. I live where I want, and will drive to my job.
I don't know on the 7 year thing. If it comes up in the interview, be completely honest about it, and tell them what you would have done differently if you could do it over................ or, based on what you know now / how you drive now, and what steps you have taken so that it will not happen again. Obviously it is working, as there have been no incidents since. Remember that safety is everything to Walmart, as it should be, because as a driver for them, you have a huge bullseye on your back.
Let us know if you hear anything. If you get the call for the 1st interview, understand that you beat out possibly hundreds of other drivers, just to get that interview. They do not interview a lot of people. For my job posting (they hired 5 in my batch, and there was a second batch with 1-3 hired), there were over 1000 applicants. 16 were interviewed in my batch, and 5 were hired. All 3 that interviewed on the day that I did, got hired. This was the first hiring at my DC in 6 years.
