Frequently asked questions
What skills should a Java developer put on a resume?
Core Java with the version (Java 11, 17 or 21), Spring Boot, Spring Security, Hibernate/JPA, REST APIs, SQL, a message broker such as Kafka, testing with JUnit and Mockito, and build and deploy tools like Maven, Docker and Jenkins. Use the exact names from the job description.
How do I write a Java developer resume with 2 or 3 years of experience?
Keep it to one page. Lead with a short summary, then 3–4 bullets per job showing what you built in Java and what improved: response time, volume handled, bugs reduced or time saved. Add one project if your work experience doesn't show your full stack.
Are Java certifications worth adding?
Yes, if they're current. Oracle Certified Professional (Java SE 17 or 21) and cloud certifications such as AWS Developer Associate are recognised by recruiters and match keyword filters on Naukri and LinkedIn.
Should I mention notice period or current CTC on my resume?
Usually no. Indian recruiters ask for CTC, expected CTC and notice period on the call or in the application form. Leave the resume for skills and results.
