Walmart Retails Sales Associate interview questions

The first phone call I received, was from a female supervisor that left me a message on my voice mail. She said that she received my application and if I was still interested in a position to give her a call. However when I called back and asked to speak with the lady that left the message she was unavailable several times. When I finally made contact with her, she did not remember calling or leaving me a message. She stated that she would have to find my application and call me back. over a week later she called me back and denied even calling me. Even though I had a voice mail recording with her name and position.
