Among the highlights were candidates who:

  • Painted graffiti on the building when he wasn't hired on the spot for a security position
  • Wore a Boy Scout uniform and never told the interviewer why
  • Was arrested by federal authorities during the interview
  • On the way to the interview, passed, cut off, and flipped the middle finger at the driver who happened to be the interviewer
  • Referred to himself in the third person
  • Took off his shoes during the interview
  • Asked for a sip of the interviewer's coffee
  • Told the interviewer she wasn't sure if the job was worth "starting the car for"
