  1. Hiver's core feature is transforming a standard Gmail inbox into a collaborative shared inbox. Describe the key architectural components you would design to enable real-time email assignment and status updates (Open, Pending, Closed) across multiple agents, ensuring low latency and high consistency, especially given Gmail's API limitations and event push mechanisms.

    Software EngineerSystem DesignTests: Evaluates understanding of distributed systems, real-time processing, API integration challenges, and data consistency.

  2. An agent using Hiver assigns an email to a colleague, but the assignment takes several seconds to reflect in the colleague's shared inbox view, leading to potential duplicate work. Outline a debugging strategy to identify the root cause, considering factors like network latency, Gmail API rate limits, backend processing queues, and frontend rendering issues.

    Software EngineerDebuggingTests: Assesses problem-solving skills, systematic debugging approach, and understanding of common distributed system bottlenecks.

  3. Hiver allows customers to create complex automations based on email content, sender, or subject (e.g., auto-assigning emails with 'Urgent' in the subject to the priority queue). Design a scalable and efficient rule engine that can process millions of incoming emails per hour against potentially thousands of unique customer-defined automation rules, minimizing processing latency.

    Software EngineerSystem DesignTests: Evaluates knowledge of rule engine design, data structures for fast lookups, and distributed processing strategies.

  4. Hiver's analytics dashboard provides metrics like 'First Response Time' and 'Resolution Time'. Given a stream of email events (sent, received, assigned, marked closed) from a shared inbox, write a function or describe an algorithm to accurately calculate the First Response Time for a specific email thread, considering only agent replies and excluding auto-replies or internal notes.

    Software EngineerCoding/AlgorithmTests: Checks logical thinking, ability to parse event streams, and handle specific business logic requirements for metrics.

  5. Imagine Hiver is launching a new feature: AI-powered email categorization that suggests which shared inbox an incoming email should go to. Describe how you would integrate this machine learning model into Hiver's existing email processing pipeline, considering latency, fault tolerance, and the ability to update the model without downtime.

    Software EngineerSystem Design/MLOpsTests: Assesses understanding of integrating ML services, asynchronous processing, and deployment strategies for AI models.

  6. Hiver's 'Collision Alerts' feature notifies agents if another agent is already viewing or typing a reply to the same email. How would you design a real-time presence system for this, ensuring minimal resource consumption from Gmail API calls and high accuracy for thousands of concurrent users across potentially millions of email threads?

    Software EngineerSystem DesignTests: Evaluates knowledge of real-time communication protocols (WebSockets), caching, and distributed presence systems.
