have anyone met any interviewers who are really sucks big time?

Yes... most financial companies have such attitude, especially interviewee from an Engineering background wanted to go into Financial industry. They will tend not to understand engineering terms (though such positions offered from them is like Customer Engineer or Quality Engineer) and at the end saying you are wrong in any sense. There are some I met who are quite cocky, especially when they think their English language is so superior, which I don't think they are.
