I have read this question Is it better to write a good cover letter in English or a mediocre one in the local language? but this is a different scenario.
Often, one of the requirements demanded on job posts in my country (previous question is in a foreign country) is advanced level of English. In these cases, should I send my resume written in English (indicating my level as well), or is it better to just send my resume written in the local language and indicate my level of English?
When you should write your CV/Resume/Cover letter in English:
When you should not write your CV/Resume/Cover letter in English:
Even if English knowledge is required for your position, it does not mean that the person who should review your CV/Resume/Cover knows English.
You can also send your information in two languages. But i'd not suggest to do this if you are asked to send it in specified language.
Just because the position you apply for requires an advanced level of English doesn't necessarily mean that everyone in the company requires an advanced level of English.
Providing a resume both in the local language and in English provides accessibility to HR or other employees who may need to evaluate you but aren't as knowledgeable of English.
Points F0G addressed above are good guidelines.
However, one must also consider that depending on the size of the organisation. They may have a few (if not more) members of staff who's level of english is at full professional proficiency . If that is the case, writing your resume in english would be your best option. Trying to translate your intent and purpose will always not transpire well with such matters. As the saying goes it may get 'lost in translation'.
Secondly, let us not forget that some international companies outside of english speaking countries (US,CAN,UK,AUS,NZ,etc). Also hire native speakers (in this case english) with the intention of strengthening their communication barriers abroad in conjunction with their applicants secondary or tertiary language skills as an intermediary communication base in their branches abroad. Either way, unless it is explicitly stated that a translation is needed. It isn't required to do so.
Personally having written my own CV/resume solely in english to the middle east and africa. I did not have any issues when it came to interviews nor the application processes.
Good luck!
So the fact is: You are an excellent English speaker, and at most mediocre speaker of the native language. Either that is acceptable for the position that you wish to apply for, or it isn't. If it isn't acceptable then you won't get the position, no matter what you do. How you write your CV won't make a difference. So logically, we can exclude that case.
Based on the assumption that they are happy to hire someone with excellent English but mediocre native language I'd write the CV in English. If possible I'd add a cover letter in the native language - just in case your CV arrives in the postroom of the company with someone who wouldn't have a clue what this letter is otherwise, to make sure it actually goes to someone reading English.
I'd say if there is nobody who can read your English CV, then you won't be getting the job anyway, so write it in English.
