We know that 85% of the information that a human being receives through the 5 senses, at any one moment, is visual

We know that an employer decides whether to hire you or not in a maximum of 4 minutes (sometimes only 30 seconds).  That's not much time for a logical decision - it's instinctive.

Therefore 85% of a an instinctive 4 minute decision about your future will be visual - what they see of you. Not what they hear.
