just as for eplanation:
There is a company here in Germany who offers a temporary job in the USA. I wrote a letter of application in german and as for a proof of my english skills I´d like to add a second letter in order to give the employer an idea about my english skills. the text as follows:
Dear Mrs. …,
since the above mentioned job holds true for a job in the USA and a good command of the english language is needed I´d like to give you a proof of my skills in addition to my application in German. On my last job as project-manager I quite often had to use my english skills in negotiations with and explanations to customers and subcontractors on different levels. For sure I might lack some expert terms needed on the specific job, though I think my basics are suitable and easily improvable for a successfull doing the job.
Additionally to my profesional use of the english I also practise the language on two different teaching sites as are: https://forum.english.best/c/english-as-a-second-language/what-do-you-want-to-talk-about ( my nickname is miot) and https://www.myenglishclub.com/chat (nickname zivi). The first one provides members with a higher level of the language and the second one requests intercultural skills and tolerance.
Now, you might wonder why I apply on this job offered in particular. There are different reasons.: Atfirst, , as I mentioned in my german letter of application, that position attracts me and I feel well armed (ready) to take the professional challenge you offer and describe. Secondly, your offer provides me with the chance to work abroad and practise my intercultural skills. And last but not least, since the time span is limited to 5 years I could retire after fulfilling this time span. My last reason might appear a bit selfish, but you yourself mentioned during our call on the phone this option.
I hope i am able to convince you of my english skills with this part of my application and give you another reason for a personal interview.
I look forward to reading from you.
I´d be glad to know your opinion about it and also receive corrections, where required.
Thank you in advance
