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?

Let's walk through a past project you've worked on. I'm interested in understanding your approach, the challenges you faced, and how you overcame them. To start, please describe a project where you had significant ownership and responsibility. Elaborate on the project's goals, your specific role, and the technologies you utilized. For example, perhaps you led the development of a new feature for a mobile application using React Native, or you were responsible for optimizing a database query that was causing performance bottlenecks. As you describe the project, please highlight the key decisions you made and the rationale behind them. I'd also like to hear about any unexpected obstacles you encountered and the steps you took to address them. This could include technical challenges, team coordination issues, or changes in project requirements. For instance, how did you handle a situation where a critical dependency was deprecated, or when a team member was unable to complete their assigned tasks? Finally, I'm keen to learn about the outcomes of the project and how you measured its success. What were the key performance indicators (KPIs) that you tracked, and what were the results? Did you achieve the project's goals, and what lessons did you learn from the experience? Please provide specific examples and quantify the impact of your contributions whenever possible. This walkthrough will help me understand your problem-solving skills, technical expertise, and ability to work effectively in a team environment.
