You run an A/B test at Google to test a new recommendation algorithm for YouTube. What statistical tests would you perform to ensure the test results are valid and not due to random variation?
Write a function in your preferred programming language to find the nth element from the end of a linked list. Explain your solution and its time complexity.
Describe a comprehensive approach to disaster recovery for a mission-critical service, detailing how you would ensure both rapid failover and minimal data loss.
How do you handle race conditions in concurrent systems?
Write a JavaScript function utilizing Puppeteer to perform end-to-end testing for a web application.
How would you implement a JavaScript function to detect cycles in a directed graph?
Imagine an application exhibiting intermittent freezes and you suspect the issue is related to memory management. How would you go about diagnosing potential memory leaks in this scenario?
Describe your approach to managing and verifying asynchronous operations in test scripts using Protractor for an Angular application. How would you ensure that these tests execute reliably in a continuous integration environment?

How would you take advantage of asynchronous patterns in JavaScript to improve the responsiveness of a web application while ensuring key features like video playback remain smooth?
How would you approach debugging a front-end application that handles high-frequency data fetching, given reports of unusually high CPU usage during peak processing?
Can you explain how you would implement infinite scrolling in a React application, and what data structures might be useful for managing the list of items displayed?
A JavaScript application you are working on has poor performance when rendering long lists of real-time updates. How would you approach identifying and mitigating rendering bottlenecks?
How would you identify and resolve a memory leak in a JavaScript web application that becomes unresponsive over time due to high memory consumption?
