The point is not to know the answers to questions but instead to know QA theory. There are too many ways to ask the same thing that you would learn answers to, and you would still not understand it was the same question many times over. If you are lucky enough that the person asking the question is gullible then you have just gotten yourself a ticket to hell. Why would you want to be hired to do a job that you do not understand when it is so much easier to first learn to understand the job, and then to have the answers at your fingertips. Oh, not because you studied the answers, but due to the fact that you know your stuff.
You are in the right place to start reading, and follow links to suggested sources of detail.
To add to what Frits said - you also need to learn how to interview for a position - it is not just being able to answer questions with a specific answer it is:
- being able to interpret the question to your own experience and provide an answer based on that which*will fit the questioners realm of understanding
- being able to positively answer questions when you do not have the specific knowledge or answer that an interviewer is looking for
- being able to get someone to buy the experience you have for the position that they want to fill
Look around for books and articles on interviewing techniques.

Just have a browse around and look at the topics covered in this forum, this will give you some idea of the scope of knowledge you will need. A bsic knowledge of much of this is required.
Admittedly, much of this will come with experience and you never stop learning.
Unless you're actually implementing what you learn in a job, reading will only give you a background on the theory and maybe help you fool someone that you actually have the experience. This forum isn't really oriented toward helping someone get a job. Be honest with what you already know and get an entry-level job that matches the level of experience you have and move up from there. You can learn a lot from the knowledge here and there are already many posts on how to properly interview and get started in the QA field if you search for them. Searching is sometimes difficult, but if you're really serious you might even actually read every post that sounds interesting in the general/functional/automation/web-testing forums from top to bottom.
