Já estava bem razoável, Pedro. Eu dei mais uns retoques:
April 20, 2014
I am writing in reply to your advertising found on the Continental Job Careers website. I would like to apply for the position you have posted.
I am 21 years old and come from São Paulo, Brazil. I have been studying Industrial Engineering since 2011. In 2013 I was in Ireland on an exchange, during which time I attended a six-month English course that complemented well my previous and ongoing studies in Brazil.
At present, I am an intern at Continental Brazil in Process Engineering, Commercial Vehicles Division. I work mainly with tachographs (MTCO, KTCO, and VDR Brazil), but also in other projects of CV that are currently in production, as well as in projects that are in development.
I feel I would be suitable for the position because I have some experience with tachographs acquired during my internship in Brazil, and am familiar with the Continental environment.
I appreciate your attention and look forward to providing any additional information you may require.*
