I've had this question before too. I was told to tell a potential employer what I can do for the company. Do some research on the company. Give them more specific information about how you can help them. For example, "I am the best person for this job because I have a plan on how you can increase revenue in England." Or, "I have experience working as a manager and I know what I can do to help your team." The more specific you can be the better. Here is a correction of your text :) Because I am the best person for this job. And I’m not afraid to say so. I know this job fits my skills. I like teamwork. I'm prepared for this job. I know how to work under pressure. I´m practical and I have good leadership skills. I´m a very hard working person.

Let me reinforce the two key principles of interview answers that have been mentioned. 1. Tell them what the benefit to them would be if they hired you, being as specific as possible. 2. Back up your assertions with concrete examples. And 3. Keep your answers short and to the point. And whether you are asked this specific question or not, you must include these benefits and your supporting evidence somewhere in your interview answers. If you leave the interview and they don't have a firm idea of why they should hire you rather than someone else, you've wasted the interview. Good luck!

but Amanda already said that :)...good luck!

it is also recommendable to back up your answers, not to say only that you're a good team worker but also explain why, for example have you ever engaged in any team activity before, played team sports in high school...

This is a very efficent way to answer tricky question!
