I had 4 rounds.
The first round involved explaining the technical aspects of my current projects, technical questions on Core Java, Struts2, Hibernate.
Second round involved security related questions like PADSS, PCIDSS compliance questions & how to configure those settings in Struts2 applications.
In the final round I was asked Core Java Questions & then asked to make a simple web-application using Struts2 & Hibernate from scratch.
