KBR interview questions

had two rounds of interview ,one was technical phone and the other was on the video conference room,..telephonic interview was successful but the next they went in detail in the module which I dont have experience..

I have been interviewed by HR Manager, HR recruiter, IM Manager and SLM Manager on conf call(as he based in UK). HR Manager has described the company history and project overview, then, I have been asked to tell about myself, later HR has asked some questions and IM Manager has asked some other questions and fianlly SLM Manager asked a couple of questions and has give a scenario where I had to provide a solution.
