Let's discuss the intricacies of implementing a doubly linked list. How would you approach designing a doubly linked list class, considering the core functionalities such as insertion, deletion, and traversal in both forward and reverse directions? Illustrate with examples how you would handle edge cases, such as inserting at the beginning or end of the list, or deleting the only node in the list. Specifically, walk me through the code you would write for an insertAfter method, which inserts a new node after a given node, and analyze its time complexity. Furthermore, explain how you would prevent memory leaks when removing nodes from the list.

Let's design the LinkedIn feed. Consider the user experience, key features, scalability, and personalization aspects. For instance, how would you prioritize content from connections versus suggested content? How would you handle different content types like text, images, videos, and articles? How do you design a system to ensure that the feed remains responsive even with millions of active users? How would you personalize the feed to show users content they are most likely interested in, and what data would you use to achieve this personalization? Finally, how would you prevent the spread of misinformation or harmful content within the feed?

Or maybe you admire the company's culture and values, such as its emphasis on transformation, integrity, collaboration, and results. It would be helpful to hear about specific projects or initiatives at LinkedIn that resonate with you. Have you been following LinkedIn's work in AI, education, or small business support? Are there any particular LinkedIn products that you find innovative or impactful? Are you inspired by the work of a specific team? Furthermore, how do you see your skills and experience aligning with LinkedIn's goals? What unique contributions do you believe you can make to the company, and how would working at LinkedIn help you grow professionally? I'm interested in understanding how your personal values align with LinkedIn's core principles, and why you believe this is the right place for you to advance your career.
