I thought this place was very unprofessional as I'm waiting for an hour on my interview there are people in the HR office cussing and talking about drugs and as I'm sitting there before the other person that was there to be interviewed the lady came out looked at me looked at them and called them back and I feel that it was because they was Mexican and will work for a lower rate I did not continue with the interview and will not go back
