Funny how deciding what to wear is often the last thing people consider when preparing for an informal job interview. Rather, candidates fill their head with the correct answers to probable questions, contact references and research the company instead of contemplating the most important detail of them all - attire. The right outfit will make all the difference in landing an offer. Informal job interviews, while casual, still need to be representative of the conservative American workforce. Interviewers look at you as a package and will decide whether or not you will fit into the climate of their business setting.
