We've recently advertised vacancies we have at my school.
I would suggest that job-seekers apply their alleged skills in English to that initial contact email and try to show themselves in the best light possible. I have been stunned by the generally poor quality of application emails sent. Surely people must realise that the very first point of contact with a potential new employer is the email? Forwarded content, the word 'Hi' with a grainy picture and a out-of-date document, awful grammar and self-inflated egos (without proof) don't really cut it.
Perhaps prospective employees should concentrate more on that first email, which might result in fewer rejections.
