6,030 java senior interview questions shared by candidates

There're always technical questions related to java. Almost always there's a question about HashMap in java and relation between hashCode and equals. Other standard questions are related to JUnit, TDD, design patterns. Basic knowledge of SQL is also checked. Be careful with Spring and Hibernate. Don't put in CV too much - don't write all acronyms you've ever seen - you'll be asked detailed questions about them.
