Practice questions in Garmin's style

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

  1. Imagine a user is reporting that their new Garmin Forerunner watch is consistently losing GPS signal during their marathon runs. How would you approach debugging this issue, considering both software and hardware factors?

    Software EngineerDebugging, Hardware InteractionTests: Assesses problem-solving skills, systematic debugging, and understanding of embedded systems and sensor data.

  2. We're developing a new feature for Garmin Connect that allows users to automatically sync historical activity data from a competitor's platform. Design the system architecture for this data ingestion and processing pipeline, considering potential data format inconsistencies and large historical volumes.

    Software EngineerSystem Design, Data PipelinesTests: Evaluates system design capabilities, handling of large data volumes, and error handling for external integrations.

  3. A user reports that their Garmin Edge cycling computer randomly reboots during long rides. Walk me through your thought process for identifying the root cause. What logs would you look for, and what potential software or hardware issues could be at play?

    Software EngineerDebugging, Embedded SystemsTests: Tests debugging methodology and understanding of potential failure points in real-time embedded systems.

  4. Write a Python function to process raw GPS coordinate data from a Garmin device and identify segments of the activity where the user was stationary for longer than 5 minutes. Assume the input is a list of tuples (timestamp, latitude, longitude).

    Software EngineerCoding, Data ProcessingTests: Measures coding proficiency, algorithmic thinking, and data manipulation skills.

  5. How would you design a real-time notification system for Garmin Connect that alerts users when they've achieved a personal best for a specific activity (e.g., 5k run, 100-mile bike ride)? Consider the scale of millions of users and activities.

    Software EngineerSystem Design, ScalabilityTests: Assesses ability to design scalable, real-time systems and handle event-driven architectures.

  6. You're given a dataset of user activity logs from Garmin devices. Write a SQL query to find the top 10 most active users based on the total distance covered across all their activities in the last month.

    Data ScientistSQL, User Activity AnalysisTests: Evaluates SQL proficiency and ability to extract meaningful insights from user data.
