Pre-Screening Video Interview Questions for Robotics Software Engineer

These pre-screening video interview questions are ideal for one-way video interviews on ScreeningHive. Use them to quickly evaluate technical fit, communication, and problem-solving before scheduling live interviews.

1. Introduce your experience with robotics software and highlight the two most relevant projects you worked on.

   This evaluates overall experience, role fit, and communication clarity for initial screening.

2. Describe your experience with ROS or other robotics middleware and a specific problem you solved using it.

   This checks practical familiarity with middleware, problem-solving ability, and hands-on knowledge.

3. Explain how you approach sensor calibration and one tool or method you use for calibration tasks.

   This assesses attention to data quality and practical techniques for ensuring reliable sensor inputs.

4. Provide an example of a performance bottleneck you encountered in a robot system and how you optimized it.

   This reveals profiling skills, optimization strategies, and impact on system performance.

5. How do you ensure safety and reliability in deployed robot software? Give one concrete practice you follow.

   This measures understanding of safety processes, testing, and coding practices relevant to production systems.
