The real victim is the public that fly on these flights under the belief that current CX/KA pilots have an operational level of English.
Are you being serious?
After 5 years at CX not once have I thought another pilots English was even slightly unsatisfactory.
How many years have you been flying for CX?
If the answer is none, which I think is highly likely, you need to wind your neck in as obviously do not know what you are talking about making comments such as that.
If someones English is not satisfactory I highly doubt they will only fail because of the ICAO test. The interviews are all in English, if it is not up to standard this is where the biggest problem with language skill will be.
