By throwing this question, the interviewer wants to inquire into your versatility and ability to manage various social media platforms differently instead of treating all the platforms as just one unit.   You need to give a brief introduction about LinkedIn and its audience base. LinkedIn is used by mostly professionals so you need to plan and create content where you can share advice, concepts, and techniques with your niche audience. You can also connect with relevant groups, foster them and share industry news among your groups.   To grow your business page there, talk about optimizing it so that it can appear in the search results. You should also post regularly, create worthy and engaging content, communicate with your audience, and sometimes run ad campaigns to catch more eyeballs and clicks on your content. Once done correctly, your brand reaches more people automatically. Since LinkedIn is the leading B2B channel used by marketers, it can be beneficial when you want to target businesses.
