  1. Imagine a user wants to find all customer accounts in California that have spent more than $10,000 in the last quarter, and has a support ticket open. How would you design the ThoughtSpot query to efficiently return this information, considering potential data warehousing and indexing strategies?

    Software EngineerQuery Optimization & Data ModelingTests: Evaluates understanding of database performance, indexing, and efficient query construction in a data analytics context.

  2. ThoughtSpot processes large volumes of analytical queries. Describe how you would architect a distributed caching layer to reduce latency for frequently accessed aggregate data, considering cache invalidation strategies for near real-time data updates.

    Software EngineerSystem Design: CachingTests: Assesses system design skills for distributed systems, focusing on caching mechanisms and data consistency.

  3. A user reports that a dashboard they built in ThoughtSpot is suddenly loading much slower than before, taking over 5 minutes. What are the potential causes, and how would you systematically debug this issue?

    Software EngineerDebugging & Performance AnalysisTests: Tests debugging methodology, problem-solving skills, and ability to diagnose performance bottlenecks in a complex application.

  4. ThoughtSpot's architecture likely involves numerous microservices. How would you design an API gateway to handle authentication, rate limiting, and request routing for a service that serves live query results?

    Software EngineerSystem Design: Microservices & API GatewayTests: Evaluates understanding of microservice architecture, API gateway functionalities, and distributed system patterns.

  5. Describe the data flow from a user executing a search query in ThoughtSpot to the data being visualized on their screen. Highlight the key components and potential performance bottlenecks at each stage.

    Software EngineerArchitecture & Data FlowTests: Assesses understanding of the end-to-end system architecture and the ability to identify performance critical paths.

  6. You are tasked with implementing a new feature in ThoughtSpot that allows users to collaboratively edit search queries. How would you handle concurrent editing and ensure data integrity?

    Software EngineerConcurrency Control & Data IntegrityTests: Tests knowledge of concurrency control mechanisms and strategies for maintaining data consistency in collaborative environments.
