YouTube has taken great strides in ensuring that they have a very diverse and inclusive workforce and will continue to do so into the future. Because of this, the team that you will be joining at YouTube will be filled with colleagues from many different and culturally diverse backgrounds. In asking this question, your interviewing ultimately wants to hear that you can thrive and that you genuinely value working in this type of environment. As you answer, talk about your experiences in working within a diverse organization and explain the great things that you've learned along the way that will help you quickly adapt to this new environment at YouTube. Suppose you haven't had any direct experience working with people from a diverse range of cultures. In that case, you can give the interviewer confidence by mentioning examples of your ability to be fair and consistent, and sensitive.
