  1. Design a highly available and fault-tolerant data synchronization flow between a customer's on-premise Oracle ERP and NetSuite using integrator.io. Focus on how you would handle network latency, API rate limits from both systems, and ensure data consistency even if one system experiences downtime.

    Software EngineerSystem Design & ReliabilityTests: Evaluates understanding of distributed systems, error handling, idempotency, and Celigo's platform capabilities in complex integration scenarios.

  2. A customer reports that their Shopify orders are occasionally missing item-level discounts when syncing to NetSuite via their integrator.io flow, but the total order amount is correct. Describe your debugging process, what tools you'd use within integrator.io, and potential causes for this data discrepancy.

    Software EngineerDebugging & Data IntegrityTests: Assesses debugging methodology, familiarity with integration data flows, and understanding of data transformation issues common in e-commerce to ERP syncing.

  3. Celigo's integrator.io allows users to define custom data transformations using Javascript. Given a large JSON payload from a Salesforce query that needs to be mapped to a NetSuite record, write a Javascript function within the integrator.io context that flattens a nested array of 'lineItems' and renames keys to match NetSuite's schema, handling potential missing fields gracefully.

    Software EngineerCoding & Data TransformationTests: Examines coding proficiency, ability to manipulate complex data structures, and understanding of error handling in data mapping scripts.

  4. How would you design a robust versioning and rollback system for integration flows on integrator.io, considering that flows can have custom Javascript, complex data mappings, and dependencies on external API changes? What are the key challenges, and how would you mitigate them?

    Software EngineerSystem Design & Software Engineering PrinciplesTests: Probes understanding of configuration management, release engineering, and impact analysis in a low-code integration environment.

  5. Celigo's platform needs to support connectors for hundreds of different SaaS applications, each with unique API authentication methods (e.g., OAuth 2.0, API Key, Basic Auth). Describe how you would design a generic, extensible framework for managing these diverse authentication credentials securely and efficiently within integrator.io.

    Software EngineerAPI Security & ArchitectureTests: Evaluates knowledge of authentication protocols, security best practices, and extensible software architecture.

  6. A customer is experiencing intermittent performance issues where their high-volume inventory updates from a custom WMS to NetSuite are taking significantly longer than expected during peak hours. Outline your approach to diagnose the bottleneck. What specific metrics or logs would you examine within integrator.io and potentially on the connected systems?

    Software EngineerPerformance & DebuggingTests: Tests diagnostic skills, understanding of integration performance factors, and ability to use monitoring tools.
