The interviewer is not particularly interested in your favorite brand but in your knowledge of the best strategies. They want to know if you can pick up a brand, and justify your choice in terms of its marketing. Portray how you love a particular brand because of its out-of-the-box thinking and its ability to generate great revenue. For this, you have to do some research about the brands with the best marketing strategies and imbibe it in your answer while keeping it relevant to the company you are interviewing for. Assure the interviewer that you plan to follow this creativity and help similarly generate profit for the company.   You can select a brand, and talk about its algorithms and how it targets its audience. Explain why they were able to grow multifold with a great strategy. You can discuss the social media presence and how it elevated the brand image while also leading to the profit.
