This is an intriguing question, in that it can refer to either the industry in which one works, or the particular role one performs, depending on the individual’s circumstances. For example, not everyone is allowed to speak openly about their work due to confidentiality, non-disclosures and fiduciary concerns. No problem. When asked this question, people in the tech industry often answer, “I’m building the future.” Or, “I’m working on making everyone’s life easier,” because of the limitations to what they can say regarding their actual work. If you’re a doctor, lawyer, plumber, or otherwise occupy one of the many “job titles” easily defined by a single word or phrase, you’re golden. But for most folks, providing a brief and concise description of the type of work you perform should be an acceptable response. There are so many job titles that exist today that no one had conceived of 20 years ago, so if you fill one of those types of roles, some defining of what you do becomes necessary. Regardless of your title, provide some details that link what you are already doing and its relevance to the job you are trying to fill. Describe the most typical functions you know are necessary for success for that next position, express industry knowledge and awareness, and how you will fill the role professionally for that company.
