When all candidates alike have to write Greek or Latin
verse, it is relatively easy to decide which verse is the
best. Men thus selected on their classical performance were
then sent forth to govern India. Those with lower marks
were retained to govern England.
The current "system" for getting hired might be arbitary and unrelated to programming ability, but it does at least present a consistent and knowable environment in which candidates have to operate. So you have to question the judgement of someone who makes basic errors like this.
I think if I saw a CV written by someone who's first language was not English I'd be a lot more forgiving of grammatical errors, but that is an edge case and not the point of the OP.
