A suit is not always the best choice for what to wear on a job interview. If you show up wearing a suit and tie and all the employees are wearing shorts and flip-flops, you will look out of place, feel uncomfortable and give off the wrong energy. The same is true of the opposite. If you show up wearing shorts and flip-flops to a company that wears professional attire, you will be just confirming that you don’t fit into the company.
