Wouldn't it be better to learn about that stuff, so that you can answer those questions from your own knowledge? Otherwise, what happens in an interview if you get a question you don't know the answer to?
But I think its not easy to get Portal Designer from net. And WebSphere Portal Server too. And I have opportunity to get work in that. But before that I need to clear the interview for WebSphere Portal. Thats why I asked for questions and answers
A good use of your time might just be going over the various posts in this forum. There's lots of good questions in here, and most of the questions apply equally to WebSphere as they do to other portals.
