To whom it may concern,
I am writing to express my interest in the position offered by you, which I recently saw advertised in your profile.
As far as English skills, last year, I completed the First Certificate in English from the University of Cambridge and now I am studying to apply for the C1 advanced Exam. Moreover, I always help my sister with her Speaking in order to develop her communication skills
On the other hand, people often describe me as a hard working man who try to do his best. Therefore, I consider I would be a good fit for the job.
I am available for an interview at any time. Please, do not hesitate to contact me for further details.
I look forward to hearing from you soon.
Yours faithfully, Santiago
