Это не резюме, это называется covering letter на британском и cover letter на мириканьском английском. Кстати по этим словосочетаниям в гугле тонны образцов.
Dear Mr. Robinson,
Your job advertisement in Time Online from 04 April 2011 has aroused my interest. I would like to meet the challenge as a legal research assistant (was there something about the challenge in the ad? Maybe just "I am very interested in the position of the legal research assistant"?). My skills and abilities match the profile of requirements listed in the advertisement. Needless to say, I am convinced that the position would open for me more exciting career opportunities later on.
My excellences are to advice the customers friendly and competent.
Ничего не поняла. Что ты этим хотела сказать?
I always stay professional and objective in difficult situations. Due to my enthusiasm and high motivation to learn new skills, I am able to quickly adapt to new business areas and start working within them autonomously and independently in a short time.
Due to my current studies in environmental and business law and my previous experience I think I would be the perfect candidate for this job. I would be very pleased to receive an invitation to attend an interview.
Sincerely yours,
А насчет предыдущего опыта в объявлении ничего не было? Имхо надо написать, как и где ты себя уже проявила.
