What to Focus On

1. GCP

GCP is one of the strongest signals in this job description. Prepare practical cloud knowledge rather than only terminology—deployment, compute, networking, IAM, monitoring, logging, scaling, and application integration.

2. Spring Boot & Microservices

Be prepared to design and explain production-grade Spring Boot microservices, including API communication, configuration, security, error handling, logging, resilience, and deployment.

3. Production Support

This isn't purely a development position. You should be able to explain how you investigate production incidents, analyze logs, identify root causes, perform fixes, and maintain business-critical applications.

4. OpenShift

Prepare how Java/Spring Boot applications are packaged, deployed, configured, monitored, and scaled on OpenShift.

5. Enterprise Java

Core Java, Advanced Java, Spring MVC, JDBC, and Web Services indicate that the interviewer may test both fundamentals and enterprise application development.

6. Testing & Quality

Prepare JUnit, Postman, functional testing, code-quality checks, and security scanning. Understanding how testing fits into CI/CD will be valuable.

• 8+ years: Confirm that your experience is directly relevant to Java/J2EE and enterprise application development.
• OpenShift: Prepare practical deployment and troubleshooting experience.
• Spring Boot + Microservices: Expect these to be core technical interview areas.
• Production support: Have real examples of incidents, RCA, fixes, and system maintenance.
• Spring Security: Be prepared to explain authentication, authorization, filters, and API security.
• Testing: Make sure you can discuss both JUnit and functional/application testing.
• Security tools: SonarQube and Checkmarx are preferred, so lack of experience is likely a smaller gap.
