Leave ample time for interactive Q&A—the panel wants to see how you handle unexpected technical questions.

Q: What differentiates candidates who get offers from those who do not? A: The most successful candidates are "full-stack" researchers. They can write elegant mathematical formulations on a whiteboard, implement those equations in clean PyTorch code, debug a hardware latency issue on a robot, and explain the entire system clearly to a peer.

• Focus on First Principles: When faced with a question you do not know the answer to, do not guess. Instead, state your assumptions clearly and build up to a solution using fundamental principles of physics, math, or computer science.
• Emphasize Safety: At & General Intuition, safety in physical AI is paramount. Whenever you design a system or policy, proactively discuss how you will ensure safety, handle edge cases, and implement fail-safes.
• Show Hardware Empathy: Understand that physical hardware is messy. Acknowledge real-world issues like sensor noise, thermal throttling, network latency, and physical wear-and-tear when discussing your algorithms.

• Be Receptive to Feedback: If an interviewer nudges you in a different direction during a coding or design session, embrace it. They are testing what it is like to collaborate with you on a daily basis.
