I applied through a recruiter. I interviewed at Oracle
Interview
The process took 4 technical rounds. They asked mostly core java questions and tricky stuff in multi-threading. In further rounds they asked to solve a graph algorithm problem and to write some java code on paper for an use case. In the last round they asked sql questions for certain use cases. Over all I felt like they wanted to know if I'm comfortable with core java and know basic data structures.
