Java Developer Resume and Interview Guide: Skills to Show

Java roles often ask for Spring experience, strong fundamentals and production service skills. Your resume should show all three.

Skills hiring teams look for

List the ones you have genuinely used, and put the most relevant to the job first.

Java 8 to 21
Spring Boot and Spring Framework
REST APIs and microservices
Hibernate / JPA and SQL
Messaging (Kafka, RabbitMQ)
Maven or Gradle
JUnit and Mockito
Docker and Kubernetes
CI/CD pipelines
Cloud (AWS or Azure)

How to write your experience

Name the Java versions you have used, and the features you rely on (streams, records, concurrency utilities).
Describe services by scale and responsibility: requests, events, data volumes, ownership.
Show how you test and release: test coverage approach, pipelines, monitoring.
Keep unrelated older tools short and put current stack first.

Interview topics to prepare

Collections, concurrency and the Java memory model
How Spring dependency injection and transactions work
JPA lazy loading and the N+1 query problem
Designing for failure in microservices
Kafka consumer groups and delivery guarantees
Garbage collection basics and diagnosing performance

Tailor it to each posting

Read the job description, find the required skills, and make sure each one you genuinely have is easy to find in your summary, skills and recent bullets. Do not add skills you have not used. See the guide: how to tailor your resume to a job description, and the ATS resume checklist.
