  • As she was the only candidate, she got the job.

The conjunction so is used to talk about the effect.

Note that as-clauses are relatively formal. In a less formal style, we express the same idea with so.

As-clauses usually come at the beginning of a sentence and are separated from the rest of the sentence with a comma. Clauses introduced by so usually goes after the main clause.
