What you have here really hits a lot of key points. A few more things I would mention are this.

1. Be sincere. This means that you might have to say you don’t know, or are not sure while you’re in the interview. Just have a positive attitude and let the prospective employer know that you’re not going to let that lack of knowledge stop you. You may still lose some positions that you could have gotten had you stretched the truth a bit, but trust me, you’ll be happier, since the expectations won’t be higher than your abilities. You will find more opportunities for advancement in positions that you landed by being sincere.

2. Decide who you are. I’ve been a sort of jack of all trades, and while I am adept at most of them, I have found that prospective employers often prefer a person who knows who they are. Specialize in something and really get to know it. When people think of you, they should think of you as “the [your specialty here] person”. If you have different skills, make sure your resume and your interview target those specific skills that the position you are going for are interested in. If the interviewer wants to know if you have other skills, feel free to let them know that you do, but don’t make a big deal of them, if they are not specifically relevant to the position you are applying for. Don’t say, “I can do anything you want”, most employers will see it as a red flag.

3. Okay, here’s probably the biggest thing. Believe it or not, in my own experience, what you know is actually less important than who you are. Someone hiring wants to see that you have at least the minimum skills to do the job, but after that, they really want to see if you are the kind of person they can stand working with. You want to come in with a “Can do” attitude, but don’t be all sappy. Be confident. This may mean psyching yourself up first and imagining yourself impressing the hiring managers and landing the job before you enter the interview. Imagine them offering you more than you had in mind to ask for and see yourself accepting calmly and smoothly. Imagine working in an environment of mutual like and respect. Cement this image in your mind before entering the interview and feel it as you interview. Feel as if the right place for you to work can’t help but hire you because you’re the perfect fit.

This is an awesome article and yes the points which you have raised were very important. One think i must add in this that you should know the organizational chart of an organization this will help you to visualize your position and your work importance.
