Let's design a tool to evaluate GitHub repositories based on metrics like stars and forks. Functionality:** The tool should: Fetch data from the GitHub API (stars, forks, open issues, contributors, etc.) for a given repository. Calculate a popularity score based on a weighted combination of these metrics. For example, stars might have a higher weight than open issues. Allow users to compare multiple repositories side-by-side. Present the data in a clear and visual way (charts, graphs, tables). Allow users to customize the weights used in the popularity score calculation. Handle API rate limiting gracefully (e.g., caching, authentication). Include features for trending topics/repositories. Example:** A user wants to compare the popularity of facebook/react versus angular/angular. They should be able to enter these repositories into the tool and see a comparison table showing the number of stars, forks, open issues, and the calculated popularity score for each. The user should also be able to adjust the weight given to stars in the popularity score to see how it affects the overall ranking. Consider additional features like displaying the rate of growth over the last month/year. What are the key components, architecture, and considerations for building such a tool, and what technologies would you choose and why?

Tell me about a time you went above and beyond for a client or customer. Describe the situation, the actions you took, and the positive outcome that resulted from your efforts. What was the context? What specific steps did you take to exceed their expectations? What were the results of your going the extra mile? For example, perhaps a client was facing a critical deadline and you volunteered to work overtime to ensure their project was completed on time and to a high standard. Or maybe a customer was experiencing a frustrating issue with your company's product or service, and you took the initiative to personally resolve their problem, even though it was outside of your usual responsibilities. Consider a situation where you identified a potential problem or opportunity that the client hadn't even considered, and you proactively developed a solution or proposal that delivered significant value to them. Did you receive any special recognition or commendation as a result of your efforts?
