• Can you explain the software development lifecycle (SDLC)?
  Understanding the SDLC is fundamental in managing projects effectively.
• Describe an object-oriented programming concept.
  Expect candidates to illustrate concepts like inheritance, polymorphism, or encapsulation.
• What is the difference between synchronous and asynchronous programming?
  Asynchronous programming is essential for high-performance applications; candidates should articulate its advantages.
• How do you ensure code quality and maintainability?
  Look for answers highlighting the importance of code reviews, testing, and documentation.

Database Management

Since financial applications handle extensive datasets, expertise in database management is critical.

• What experience do you have with SQL vs. NoSQL databases?
  Understanding both types of databases provides a competitive edge in application development.
• Can you explain normalization and its importance in database design?
  Normalize denormalization principles will be helpful in optimizing query performance.
• Describe a time when you optimized a database. What steps did you take?
  Seek examples of practical problem-solving and performance tuning.
• How do you handle database migrations?
  Database migrations are often necessary for scaling applications, and the candidate should demonstrate familiarity with best practices.

Technical Challenges

Technical challenges are an excellent way to assess a candidate’s coding abilities and theoretical knowledge.

Expect to present candidates with coding challenges that may pertain to solving algorithms, data structures, or even system design. Some potential challenges include:

• Design a simple banking system.
  Encourage candidates to explain their design choices, database schema, and how they plan to ensure transaction integrity.
• Optimize a given piece of code for performance.
  Provide a code snippet and ask them to improve its efficiency.
• Implement a feature to detect fraud in banking transactions.
  This would test their analytical skills as well as their understanding of real-world applications.
