Cognizant Java/J2EE Developer interview questions

Careernet Consulting processed my resume and asked me to take interview on 18th June, I got call letter from both Cognizant and careernet. When i reached the place Cognizant hiring team told that they are looking for people who know java with springs and not with Java with Struts which I had. If the requirement was for Springs, why did they call for interview. Because of this I wasted my time. When I enquired same with cognizant they have put the blame on careernet and asked to enquire them and when I asked careernet, they told me Cognizant is fine with any framework. In the end I suffered. Neither cognizant nor careernet have the courtesy to tell sorry. Very bad experience and no professionalism.

Scheduled for interview through Cognizant hr. 1st round is technical with senior person with some java basics. 2nd round also technical with questions on Java J2EE Spring Hibernate Struts JSP JDBC.
