If you're applying to jobs using LinkedIn, you might find it useful to know that it may be looking at your skills section to determine whether you're qualified for the position.
To clarify, I'm told the Top Skills identified for a job on LinkedIn link to the skills you're endorsed for on your LinkedIn profile. In other words, if the role is seeking Sales as a Top Skill, its not enough to list the keyword Sales in your profile. Its looking to see if you're endorsed for the Sales skills in your Skills & Endorsements section. So, the Top Skills are essentially serving as the ATS.
As always, LinkedIn changes frequently. However, someone confirmed to me this was the case for one of their clients.
