  1. Imagine a Twitch streamer is experiencing significant video stuttering and dropped frames. Describe how you would approach debugging this issue, considering the distributed nature of Twitch's infrastructure and potential network bottlenecks. What tools or metrics would you prioritize checking first?

    Software EngineerDebugging Distributed SystemsTests: Assesses ability to troubleshoot complex, real-world production issues in a distributed environment.

  2. Design a system to detect and mitigate abusive chat behavior (e.g., spam, hate speech) on Twitch in real-time. Consider the scale of messages processed per second and the need for low latency. What components would be involved, and how would you handle false positives and negatives?

    Software EngineerSystem Design Real-time ModerationTests: Evaluates system design skills for high-throughput, low-latency real-time applications with moderation requirements.

  3. Twitch is considering implementing a new feature that allows viewers to co-stream with multiple friends simultaneously. Outline the technical challenges and architectural changes you foresee. How would you ensure a smooth, synchronized viewing experience across all participants?

    Software EngineerSystem Design New FeatureTests: Tests ability to anticipate and design for new product features, considering technical feasibility and user experience.

  4. A popular Twitch streamer's channel consistently gets a high volume of viewers but has a low average watch time. Describe how you would investigate the root cause of this discrepancy. What data points would you analyze, and what hypotheses would you form?

    Software EngineerPerformance Analysis & OptimizationTests: Assesses understanding of performance metrics and ability to analyze data to identify optimization opportunities.

  5. Implement a function in your preferred language that takes a list of video stream URLs and returns the URLs of streams that are currently live, based on a hypothetical Twitch API endpoint that provides stream status. Consider edge cases and potential API unresponsiveness.

    Software EngineerCoding Live Status CheckTests: Evaluates coding proficiency, error handling, and API interaction logic.

  6. How would you design a system to recommend live Twitch channels to a user based on their past viewing history and subscriptions? Consider the cold-start problem for new users and the dynamic nature of live streams.

    Software EngineerRecommendation System DesignTests: Tests system design for personalized recommendations at scale.
