I had no work experience whatsoever, stated this on my resume, interviewer started giggling at me for applying for a position that I don't know what is is but I made it clear I never knew from the start so I don't see why he started cracking jokes at this problem.

brief and to the point ask me about recent work experience and if im able to perform the work task without help or assistance by others and in a timely matter. also if hired they give you a drug test the same day at clinic a few minutes away.
