Capgemini Senior Developer interview questions

Got the call from consultancy.There was online test.Then Technical round & HR Round.The technical interview was base on basic questions.but was tricky.There were so many candidates for appeared test but only few were shortlisted.test was no so difficult.No negative marking for test

First things first, if you have to take telephonic interview, then what is the point of calling the candidate to your office. Then the interviewer, to start with his intro to me ,was so proud that he was working for 6 years in Capgemini(Brownie points for loyalty). Then he was a proud java certified developer. Awesome. Then interview started and he got stuck in String comparison. He did not move ahead the term Stringpool, one of the very basic concepts of Java. He didn't understand what I was trying to tell him. And interview over with a comment that I don't even know the basics. Add to the insult of Java, he was sitting in Netherlands. Please, take the interview of the interview panel before putting them in that panel. They do nothing more than wasting everybody's time.
