Walmart Manager interview questions

Interviewed for a management position, had 4 questions that i felt I answered well. Waited almost two weeks and was told even tho i interviewed well did not get position. Asked what I could have done better, got no answer. And a few of the people that did get the position are having trouble with position.

Was given an online test...70 multible choice questions. After completing the questionaire you are told you will be contacted if jobs become available. If you fail, you are not alowed to retake for 6 months
