I remember when I was in high school I always put my best foot forward, regarding my attire for an interview. Plus my mom made sure of it, lol. I knew the culture was to dress very formal and appear executive-like. Well, it certainly helped over the years because I remember later on hearing awful stories of people appearing at an interview like they were at a beach or didn’t bother to wear the appropriate jacket.
Here’s the thing, you want to set the mood, the tone of the conversation. But if your appearance gives the impression you don’t care, well, how do you think the rest of the interview will go?
