For a job interview, it's always better to err on the side of being more formal than less. A good rule of thumb is to dress one level above the company's typical dress code. In the case of Meta, a tech company, it's likely that their dress code is relatively casual, so you could opt for business casual attire. A nice button-down shirt or blouse, paired with dress pants or a skirt would be appropriate. Avoid wearing anything too revealing or casual, like t-shirts or shorts.

In terms of what to bring, you should always bring extra copies of your resume, even if you've already submitted it online. You may also want to bring a portfolio or examples of your work, if applicable. Additionally, it's a good idea to bring a notebook and pen so you can take notes during the interview. Finally, make sure to arrive early and bring a positive attitude and enthusiasm for the position!
