Dress appropriately for the position based on the industry standard. If you will be interviewing for a position that requires professional attire at some companies, dress in your best attire to project that you are aware that this is a professional environment. Even if the client expresses that they are business casual, that doesn’t mean you should show up for an interview dressed that way. Remember first impressions go a long way. No loud ties or wild colors and try to eliminate any jewelry that will project the wrong image. That goes for hair styles and colors. You never know what will make the employer hire you over another candidate. Don’t give them a reason to reject you.
