u know those common questions they asked during interviews all those. about two weeks ago i went for this interview as a site supervisor, then as usual the common questions and all, and then he asked me one question that really caught me off guard. "what do you know about the construction industry?" well i do know the answer to that but having him asking that all of a sudden, made my mind kinda empty for a moment and i just tried my best uttered whatever that i can think of.
