Expected Answer: Look for candidates to mention regulations like GDPR, PCI-DSS, or SOX and describe how they can implement compliance through audits, documentation, and security protocols.

7. Can you describe your experience with Basel III and its implications for banking software development?

Expected Answer: Candidates should recognize Basel III’s role in risk management and how it affects capital adequacy, encouraging developers to prioritize stability and risk assessment in their applications.

Problem Solving and Systems Design

Problem-solving abilities are essential for a software developer. Here are questions to gauge a candidate’s analytical skills:

8. Describe a system you designed to manage real-time transactions. What challenges did you encounter?

Expected Answer: A strong response should include architectural design choices, performance testing, and strategies used to overcome bottlenecks or delay in transactions.

9. How do you handle legacy code while developing new features in a banking application?

Expected Answer: Candidates should discuss techniques like gradual refactoring, the introduction of microservices, and ensuring backward compatibility, ensuring the robustness of ongoing operations while fostering innovation.

Soft Skills Assessment

In addition to technical skills, soft skills are critical in software development roles within banking. Consider these questions:

10. How do you communicate complex technical issues to non-technical stakeholders?

Expected Answer: Listen for the candidate’s methods in simplifying technical jargon, using metaphors, or creating visual aids to clarify concepts for individuals who may not have a technical background.

11. Describe a conflict you encountered in a project team. How did you resolve it?

Expected Answer: Candidates should illustrate their collaborative skills, emphasizing active listening, empathy, and finding common ground to reach a resolution beneficial for all parties involved.

The Future of Banking Technology

As the financial landscape continues to evolve, understanding emerging technologies is beneficial. Here are some forward-looking questions:

12. What is your opinion on the role of Artificial Intelligence and Machine Learning in banking?

Expected Answer: Strong candidates will explain how AI and machine learning can enhance customer experience through personalization, fraud detection, and automated decision-making processes.

13. How do you stay updated with the latest technology trends in banking?

Expected Answer: Look for candidates who demonstrate a commitment to lifelong learning through attending conferences, participating in webinars, or completing relevant certifications.

Conclusion
