The most common reason that we do not grant interviews to otherwise qualified applicants at our company is because there is a spelling or grammatical error in their CV or cover letter. We use this screening process partly because we don't want employees who send illiterate e-mails to clients. Poor writing skills place us in a bad light. But there is also a belief within our organization that a sloppy CV indicates a sloppy worker. Since nearly everyone in our specialized mathematical field is foreign-born, we eliminate about 60-70% of CVs immediately in this way. Having dealt with many of these very smart people as clients, it's clear to me that they could improve their English skills; doing so would be less difficult than many other things they have already successfully accomplished. It's a mystery to me why people don't see that despite their technical expertise, these simple problems hold them back.
