A particular pet peeve of mine: the all-the-sudden popular and ugly-as-sin QR code. I hate them, because like many fads, most people rushing to use them don’t understand how to make sure they add value to the experience. In general, I feel that most people might as well take a poop on their résumé as put one of these on it, because adding a QR code without adding something of value to the “interview ecosystem” is well…just a load of crap.
