Practice questions in Pure Storage's style

Original ZorixOS questions written the way Pure Storage interviews, so you rehearse the real format. Not claimed as asked at Pure Storage.

  1. Imagine a scenario where a customer reports intermittent high latency on their Pure FlashArray. How would you approach debugging this issue, considering potential bottlenecks in the array itself, the network, or the host connectivity?

    Software EngineerDebuggingTests: Evaluates systematic problem-solving and understanding of storage system interactions.

  2. Pure Storage offers a cloud-based management platform. Design a scalable, fault-tolerant microservice that handles telemetry data ingestion from thousands of FlashArrays. Consider data formats, processing, and storage.

    Software EngineerSystem DesignTests: Assesses ability to design distributed systems at scale, considering reliability and performance.

  3. A customer is experiencing slow performance when running VDI workloads on a Pure FlashBlade. What are the key performance metrics you would monitor on both the FlashBlade and the VDI clients? How would you correlate these metrics to identify the root cause?

    Software EngineerPerformance AnalysisTests: Tests understanding of performance tuning in a specific application context.

  4. Write a Python function that, given a stream of block write operations to a simulated FlashArray, estimates the effective deduplication ratio. Consider how to handle varying block sizes and metadata overhead.

    Software EngineerCodingTests: Evaluates coding proficiency and understanding of data reduction techniques.

  5. You are tasked with implementing a new feature for Pure's Cloud Block Store that allows for automated snapshot tiering to cost-effective object storage. Outline the system architecture, considering data consistency, lifecycle management, and potential failure scenarios.

    Software EngineerSystem DesignTests: Assesses system design skills for cloud-native storage solutions.

  6. Describe the data path for a read operation on a Pure FlashArray. How does the array handle caching, data retrieval from NVMe drives, and ensuring data integrity?

    Software EngineerSystem InternalsTests: Tests knowledge of storage system architecture and data flow.
