No, I don't think so, but if you have to give the Test before the exam than it is mandatory for you to read the basic information or the basics of the books but the interviewer will never ask the questions from the book he/she will ask the question about your knowledge on there products or the basics of the making of their products or if you had a experience in working in their line than they will ask what did you learn untill now. Or atleast they will ask you the logical questions if they satisfy with answer you will get call back.

I do remember my technical interview they never asked me the theoritical questions but they sure did ask few basics things which we practically use everytime in C#. So if you don't have a theoritical knowledge that much but you are powerful in developing tools,forms and application than that should be enough for you to get selected.
