What to expect

I've been thinking of trying to get on with Walmart, next summer. Got 16 years, Nearly all the PSA junk from my Chicken Hauling days is gone. Have House near Los Lunas, but i noticed that W/M trks say Plainview.... would i need to live there ? Miles ? how long out ? the usual questions
Also how far back into my past will they look ? like i said i had some driver safety score issues in the past from running hard, but nearly all that's gone... a ticket hits 3 yr mark soon too....
Can some of you Walmart drivers fill me in / i've read some of the posts and will read much more in few days when i get breathing space....
Thx Cuz
