Possible Interview Questions

Can you describe a time when you had to troubleshoot a complex integration issue for a client? How did you approach it?

I once worked with a client where their system was not properly connecting to our fraud detection API. I started by reviewing logs and isolating the issue to a network timeout. I collaborated with the client's IT team to adjust firewall settings and implemented retry logic in our integration, which resolved the issue.

How do you handle conflicting priorities when multiple clients have urgent requests?

I prioritize based on impact and urgency, using a ticketing system to track requests. I communicate transparently with clients about timelines and escalate if needed. I also work with my project manager to ensure resources are allocated effectively.

Explain your experience with Java and how you've used it in a customer-facing role.

In my previous role, I developed custom Java adapters for clients to integrate their legacy systems with our platform. I worked closely with clients to understand their data formats and wrote efficient code to transform and route data, ensuring minimal latency.

Describe your familiarity with cloud platforms like AWS or Azure. Have you deployed applications on them?

Yes, I have experience deploying Java applications on AWS using EC2 and RDS. I also set up auto-scaling and monitoring with CloudWatch. For a recent project, I migrated a client's on-premise solution to AWS, reducing their infrastructure costs by 30%.

How do you stay updated with the latest technologies in fraud detection and risk management?

I follow industry blogs like the Feedzai Engineering Blog, attend webinars on machine learning in fraud, and participate in online courses on platforms like Coursera. I also contribute to open-source projects related to data streaming and security.
