Note that the exact flow and intensity can vary significantly depending on the specific global lab (e.g., Kawasaki, London, or Mumbai) you are interviewing with.

5. Deep Dive into Evaluation Areas

Past Research & Technical Presentation

Because your past work is the best predictor of your future success, a significant portion of the interview revolves around a formal presentation of your research. This area matters because it proves your ability to execute rigorous scientific methods and communicate your findings effectively. Strong performance looks like a well-structured narrative that highlights the problem, your unique approach, the results, and the real-world impact.

Be ready to go over:

• Problem Formulation – How you identify and scope a research question.
• Methodology & Execution – The specific technical tools, algorithms, or models you utilized.
• Impact & Application – How your research translates into practical applications or advances the field.
• Advanced concepts (less common) –
  • Patent drafting and intellectual property considerations.
  • Cross-disciplinary applications of your core research.
  • Scaling prototype models for enterprise environments.

Example questions or scenarios:

• "Walk us through your most impactful research project. What was the core hypothesis?"
• "During your formal presentation, you mentioned using [Specific Methodology]. Why did you choose this over alternative approaches?"
• "How would you adapt the findings from your previous work to fit into a commercial product at Fujitsu?"

Domain Knowledge & Boundary Testing

Our research teams tackle complex, multidisciplinary challenges, meaning you will often need to step outside your comfort zone. Interviewers evaluate this by probing your core skills and deliberately asking questions that push the boundaries of your expertise—sometimes even touching on seemingly irrelevant topics. Strong candidates remain calm, admit when they do not know a specific detail, and pivot to how they would logically approach finding the answer.

Be ready to go over:

• Core Domain Depth – Deep technical questions on your specific area of AI, computing, or data science.
• Problem-Solving Under Pressure – Navigating unexpected or unfamiliar technical scenarios.
• Analytical Reasoning – Structuring an approach to a problem you have never seen before.
• Advanced concepts (less common) –
  • Rapid prototyping under resource constraints.
  • Troubleshooting theoretical models that fail in practical application.

Example questions or scenarios:

• "We see your expertise is in [Skill A]. How would you approach a problem in [Unrelated Skill B] if your project suddenly required it?"
• "Assume your primary dataset is entirely corrupted. Walk me through your immediate next steps."
• "Explain a complex technical concept to someone outside of your specific research discipline."
