Can you have a look at the following text below and correct my mistakes?


I would like to apply for the position of an Assistant to the Board of your company. I think I am a well-organized person and have my interpersonal skills finely developed. I am able to work under pressure and do a lot of things at the same time. What is more, I speak fluent English and German. I am computer literate. For the last few years I have been constantly developing my skills and experience in working in various employment environments, mainly in administrative sector. I spent last three years working in London as a receptionist in a hotel. Not only had I an opportunity to take part in many training programmes but also a chance to work in a fast changing, foreign stimulating environment. It is my feeling that the time spent in London allowed to make a contribution to the work of my employers, as well as provided an excellent learning opportunities for personal development. I could know the British corporate culture better.
What will my duties/responsibilities be?
What is my job description?
What is the range of salary?
Is the salary negotiable?
Do you offer any training programmes for new employees?
Is there any possibility of being promoted?

Thanks in advance
