A couple quick do's and don't's of interviewing I learned today that I'd like to share with the general publics-

DO shower sometime during the week of your interview. You want the interviewers to remember you, not the lasting trail of BO you left behind.
DON'T come back five minutes after the interview and offer to work for free for a week. It just makes you look a little weird, and kind of desperate.
DO take your last bong hit at least 6 hours before you go to the interview. Awkwardly slow response times for simple questions like "How long have you lived in Barcelona?" are not impressive.
DON'T show up an hour early, just because you were in the neighborhood. Seriously?
DON'T scratch any body part repeatedly for more than 2 seconds. It makes the interviewer question your general health, and it's just sick.
