Possible Interview Questions

Describe your experience with Synon/Cool2E development. What types of applications have you built or maintained?

I have over 7 years of experience with Synon/Cool2E, primarily developing and maintaining claim adjudication and pharmacy benefits systems on IBM i/AS400. I have worked on high-volume transaction processing modules, including eligibility verification, claim pricing, and benefit accumulation. I also have experience in modernizing Synon-generated COBOL code for better performance and maintainability.

How do you troubleshoot and resolve complex production issues in a batch processing environment?

When a production issue arises, I first analyze the job logs and error messages to pinpoint the failure. I use tools like DB2 Query Manager and IBM i Navigator to trace data flow and identify anomalies. For resolution, I might modify Synon panels, adjust COBOL logic, or correct data inconsistencies. I also implement monitoring and alerting to prevent recurrence.

Can you explain how you would integrate a Synon-based system with external healthcare data exchanges using EDI or APIs?

Integration typically involves mapping EDI transactions (like 270/271 or 835) to our Synon data structures. I have used custom COBOL programs to parse incoming EDI files and update DB2 tables. For APIs, I would leverage IBM i's integrated web services or use third-party tools to expose AS400 data via RESTful services, ensuring HIPAA compliance through encryption and auditing.

Describe a time when you provided technical leadership to a team. How did you ensure adherence to best practices?

In one project, I led a team of four developers in a major system enhancement. I established code review standards for Synon and COBOL, conducted weekly knowledge-sharing sessions, and enforced naming conventions and documentation practices. I also mentored junior developers on debugging techniques and performance optimization.

What is your approach to legacy modernization while preserving business logic?

I balance modernization with stability by first understanding the core business logic through system documentation and SME consultations. I then create a phased plan: start with wrapping legacy programs with APIs, then gradually refactor modules using modern languages like Java or C# while keeping the Synon/COBOL core intact for critical transactions. This minimizes disruption.
