Omission of subject pronoun

As far as I know, English does not usually omit pronouns. But someone -non-native speaker of English- told me that we can omit pronouns while writing job qualifications. For example, "knows at least one foreign language". Is it possible?

I've seen that native speakers often omit subject pronouns in informal/familiar speech, but only when there is no ambiguity. I can see that the same thing occurs in Scandinavian (Germanic) languages, where verbs do not inflect for person or number just like in English.

I didn't know that omission of pronouns was allowed in writing "curricula vitae". It would be interesting to know more about it!

Another non-native speaker here I'm afraid. I do sometimes see this in things like job qualifications, when the ad is written in telegram style or using bullets.

For example:

The ideal candidate:
- is a British national
- speaks at least one foreign language
- has extensive experience in the field of IT

If whole sentences are written throughout, they need a personal pronoun. Of course, in quick emails or text messages, so very informal, they are often omitted ( "don't know - will try" ) but most people doing this will be aware it is grammatically incorrect and will (hopefully!) avoid this kind of thing in official letters...
I'd be interested in seeing other examples!

Wow this was how I responded. Thanks both of you.

this is very good post
