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?

Tell me about a time you faced a difficult conflict at work and how you handled it. To give me a clearer picture, please include the following details: Describe the situation: What was the specific conflict or difficulty you encountered? What were the core issues at stake? Identify the parties involved: Who were the individuals or groups involved in the conflict? What were their perspectives and motivations? Explain your role: What was your role in the situation? Were you a direct participant, a mediator, or an observer? Outline the actions you took: What specific steps did you take to address the conflict? Did you try to negotiate, compromise, or escalate the issue? Explain the outcome: What was the final result of your actions? Was the conflict resolved successfully, or were there any lingering issues? Reflect on the lessons learned: What did you learn from this experience? Would you have handled anything differently in retrospect?
