“The way we present ourselves can speak more eloquently of the skills we bring to the table, if we actively cultivate that presentation. Nobody likes to be crossed off the list before being given the opportunity to show others who they are. Being able to tell your story from the moment you meet other people is a skill that must be actively cultivated, in order to send the message that you’re someone to be considered and the right person for the position.”
My question is whether we can leave out “being“ in above sentence. I assume as follows;
1. If we regard this ”being” after the preposition ‘before’ as a part of a passive gerund(being given), then, the leaving out maybe not good.
2. But if we regard the underlined sentence is either a participle construction where the conjunction ‘before’ is used for emphasis, or an adverbial clause where “we are” has been omitted, then, the leaving out may be possible.
I'm not sure what you mean to say under (2) above. The truth is that you need "being" above, being short for "before they are given the opportunity ..." That is, "being" refers to the subject "nobody." "Being" can be eliminated with conjunctions like once, when, while, but is necessary after before, after.
