• How would you approach developing a new feature requested by a bank while keeping compliance and security in mind?
  This question assesses their ability to balance innovation with regulatory requirements.

Soft Skills and Team Dynamics

Finally, the ability to work effectively within a team and communicate ideas clearly is crucial in software development. This set of questions focuses on interpersonal skills:

• Can you discuss a time you collaborated with non-technical stakeholders to understand their software needs?
  Candidates should demonstrate their communication skills and ability to translate complex technical language into everyday terms.
• How do you handle conflicts in a team setting, especially when it comes to technical decisions?
  A developer should showcase their capacity for teamwork and conflict resolution.
• What’s your approach to receiving and incorporating feedback from code reviews?
  An openness to feedback and continuous improvement is a vital quality for any developer.

Current Trends and Technologies in Banking Software Development

Understanding current trends is essential for any developer in the banking sector. Here are questions that address knowledge of emerging technologies:
