ROS2
ROS2 is a modern software platform that robotics engineers use to build and control robots. Think of it as a universal language and toolset that helps different parts of a robot work together - like how the camera, motors, and sensors communicate. It's the newer, improved version of the original ROS (Robot Operating System). When companies mention ROS2 in job descriptions, they're looking for people who can use this platform to program robots for various tasks, from warehouse automation to self-driving cars. It's similar to how Windows or MacOS helps your computer work, but specifically designed for robots.

Example Interview Questions
Senior Level Questions
Q: How would you manage a large-scale robot deployment using ROS2?
Expected Answer: A senior candidate should discuss managing multiple robots, handling communication between robots, ensuring system reliability, and implementing safety measures. They should mention experience with fleet management and scaling robotics solutions.
Q: What are the key differences between ROS and ROS2, and why are they important?
Expected Answer: The answer should cover improved security, better performance for real-world robotics applications, and enhanced reliability. They should explain these benefits in practical terms with real-world examples.
Mid Level Questions
Q: How do you test and debug ROS2 applications?
Expected Answer: Should explain basic testing approaches, tools used for finding problems, and how they ensure robot behavior is safe and reliable before deployment.
Q: Explain how different parts of a robot communicate using ROS2.
Expected Answer: Should describe how sensors, cameras, and motors share information, using simple terms and real-world examples from their experience.
Junior Level Questions
Q: What is a ROS2 node and what is it used for?
Expected Answer: Should be able to explain that nodes are like building blocks that perform specific tasks, such as controlling a motor or reading a sensor, and how they work together.
Q: How do you make a robot move using ROS2?
Expected Answer: Should demonstrate basic understanding of sending movement commands to a robot and reading sensor data to ensure safe operation.
