2 person interview, typical questions ..Why you left previous employer? One question I remember was ...Do you smoke? Which I don't ...but then one of the interviewers mentions hair drug testing may be used...and then a moment of silence and stares at me to judge my reaction. I had nothing to hide and passed the drug test ok but I didn't like approach of mistrust when answering a question and the "well catch you" attitude as their response in the interview.
