I learned that Google thinks it’s perfectly fine to wear jeans and t-shirts to interviews for positions in the company. The company culture dictates that you should be relaxed and your attire should reflect your personal level of comfort. This is contrary to what I thought I knew about appropriate dress for an interview. This essentially means a student in a suit may be have been perceived as inappropriately dressed when interviewing with Google. Yet I know of student who interviewed for Google in a suit and was extended an offer for a summer internship. He told me that he was instructed to dress in attire that he felt comfortable. The position for which he interviewed was in business to business sales.
While a conservative (not black) suit is considered ideal, companies such as Google remind us that a suit is not the only option. It is crucial that you research the companies in which you have an interest. Learn as much as you can about the company culture BEFORE you interview, because you don’t want to make the mistake of wearing a suit when jeans and a t-shirt will be just fine.
