  1. Imagine Attentive is experiencing a sudden 20% increase in message delivery failures for a major client. Describe your debugging process, from initial alert to resolution, considering our SMS and email infrastructure.

    Software EngineerDebuggingTests: Evaluates systematic debugging skills in a high-pressure, production-impacting scenario relevant to Attentive's core service.

  2. Design a system to handle and process millions of incoming SMS replies per day, ensuring low latency and high throughput for real-time customer engagement. Consider data storage, processing, and potential downstream integrations.

    Software EngineerSystem DesignTests: Assesses ability to design scalable, resilient real-time messaging systems at Attentive's scale.

  3. Our platform sends billions of messages annually. How would you approach optimizing the message scheduling algorithm to maximize subscriber engagement while respecting delivery windows and minimizing processing load?

    Software EngineerAlgorithm DesignTests: Probes analytical thinking and algorithmic optimization skills applied to a core Attentive product feature.

  4. Consider a scenario where a client's SMS campaign is unexpectedly driving a high volume of unsubscribe requests. How would you investigate this from a code and system perspective, and what potential causes would you explore?

    Software EngineerDebuggingTests: Tests ability to diagnose and reason about user behavior impacts on the system and identify code-level issues.

  5. If Attentive were to introduce a new channel for customer communication (e.g., in-app notifications), what technical considerations would be paramount in designing its integration with our existing message orchestration layer?

    Software EngineerSystem DesignTests: Evaluates understanding of platform extensibility and architectural considerations for new features.

  6. Describe a situation where you had to optimize a piece of code for performance. Walk me through your approach, the metrics you used, and the outcome, relating it to improving message sending speed or resource utilization.

    Software EngineerCoding ReasoningTests: Assesses practical experience with performance optimization and data-driven decision-making.
