Sam's Club Merchandising/Member Team Lead interview questions

Applied online, took survey, then scheduled interview through automated system. Got to store and waited 20 min. Before the manager came out and told me he didn't even know I was scheduled for an interview. I never got a call regarding the merchandising lead position, but then got an interview for the member team lead position. Before I could even make it in for that interview, it showed I was no longer being considered for either position. I know I am more than qualified for these positions given my experience, but I feel like I was discriminated against because of my age and ethnicity. A very bad experience!
