It was telephonic technical interview.Quite decent .They are more process oriented. They ask complete SDLC.As a java resource you should have proper core java understanding. SDLC process. OOPS concept.DB knowledge is an added advantage. What all have you worked on your project. They go for practical implementation rather than theoretical knowledge.

1 technical round cover topics from basic java, springboot,microservices and rdbms. One coding question from stream api. 1 hr round about salary discussion. Overall average level. Focus on basics and coding skills.
