In my experience and opinion, it does not matter, as long as the application gets to the company in the end. Both the posting company and the job board benefit in situations where its posted on both. The company expands their reach by allowing those aggregators to post, resulting in the job post showing in multiple online searches, and in return, the aggregator receives web traffic which help to drive users toward advertisers. I think you’ll find that most of those career sites will redirect you to the company website once you are ready to apply!
