I applied online and the recruiter contacted me by email.

They asked me to fill out a questionnaire. All but one question were already answered in my cover letter or resume (i.e., very lazy), but I replied promptly.

The recruiter responded five days later with more questions, and I again replied promptly.

Two days later, they asked for my availability for interviews, and the day after that, they said the position was filled by "a candidate that had already completed the hiring process."

When I responded about how unprofessional their behavior was, specifically engaging candidates so late in the process when they likely were going to make someone an offer, their response was that it was standard practice for Walmart – so not even an apology.

This does not inspire one to want to work there if they treat candidates this poorly.
