Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. You can return the answer in any order. Example 1: Input: nums = [2,7,11,15], target = 9 Output: [0,1] Explanation: Because nums[0] + nums[1] == 9, we return [0, 1]. Example 2: Input: nums = [3,2,4], target = 6 Output: [1,2] Example 3: Input: nums = [3,3], target = 6 Output: [0,1] Constraints: 2 <= nums.length <= 104 -109 <= nums[i] <= 109 -109 <= target <= 109 Only one valid answer exists.

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?

Describe a time you dealt with conflict. To provide a comprehensive answer, please consider the following aspects: The Situation: Clearly describe the situation where the conflict arose. What were the circumstances? Who was involved? The Conflict: What was the specific nature of the conflict? What were the differing opinions, goals, or perspectives that led to the disagreement? Be specific about the core issues. Your Role: What role did you play in the situation? Were you a direct participant in the conflict, or were you mediating between others? Your Actions: What specific steps did you take to address and resolve the conflict? This might include communication strategies, negotiation tactics, compromise, or problem-solving approaches. Provide concrete examples of your actions and dialogue. The Outcome: What was the result of your efforts? Was the conflict resolved successfully? What were the specific outcomes, and how did they impact the team, project, or organization? If the conflict wasn't fully resolved, what were the remaining challenges? Lessons Learned: What did you learn from this experience? How has it influenced your approach to conflict resolution in subsequent situations? What would you do differently if faced with a similar conflict in the future? For example, you could describe a conflict with a coworker over project priorities, a disagreement with a client about project scope, or a conflict within a team about different approaches to solving a technical problem. Detail the situation, your actions, and the ultimate resolution (or lack thereof), focusing on the skills you employed to navigate the disagreement.
