Could you fail a job interview just for bringing an iced Americano?
In the United States, an uproar erupted after a recruitment expert stated that "applicants who show up with iced coffee may appear to take the interview lightly."
Backlash also flared up, with people asking, "Why is the interviewer's coffee fine, but the applicant's is not?"

Why has a single cup of coffee blown up to this extent?
As it turns out, there are quite a few "unseen rules" in interviews that are not written on the evaluation sheet.
From attire, tone of voice, and facial expressions, to posture while waiting... exactly how far do applicants need to pay attention?

In a setting meant to select someone who is "good at the job," are we perhaps ending up selecting someone who is simply "good at interviewing"?
Video Mug dissected the strange rules of interviews sparked by a single cup of iced coffee.
