I applied online. The process took 2 weeks. I interviewed at Walmart (Denver, CO) in Jul 2013
Interview
Went though online application process which also has you take an assessment test. Then had first and second interview at a hiring center in the same day. They definitely will ask you scenarios questions. Like, "Tell me about a time when you had a challenging project and how did you get it done?"
