And I would say you've listed those three in order of priority!!!
I don't recruit in the aviation business but I do recruit staff. The odd typo or simple spelling error I may forgive and invite the person to an interview but, if the application and CV included such ignorant errors as "peak-headed", then said application would get filed vertically downwards under B for bin!
If the original poster has language difficulties, then he should have had the maturity to admit it and apologise instead of saying that it doesn't matter. If English isn't his native tongue, then again, he should have had the gumption to ask our forbearance instead of insulting those who found it difficult to read.
