It's not a job interview. it's an SAT and simulation test for a really great job. The document says "business casual". I have most of that under control. However, should I wear a tie? I'm not sitting in front of a board. Just testing. I am wearing brown slacks, light brown shoes and belt, and a plaid dress shirt. AND funky socks. Is this enough, gents? Or do I step it up with a tie?
