LinkedIn is malware and it's frankly embarrassing that we seem to be stuck with it. It's like a mechanic being stuck with a wrench that doesn't just punch you in the face while using it, it opens your toolbox just to come out and punch you randomly.
The option I chose was "profile data" because I wanted to get my whole work history/projects/etc. for a new resume.
The export took several hours.
When I finally downloaded it, it included my name, Email, short description, and my Email address...
God I hope you are being funny. Why else would anyone install this crap?
I've never seen any ATS that required Linkedin for login, but even having it as an option I've always thought of as weird.
Then again, I have see many an ATS that include Facebook and other slop sites, so welcome to another layer of jobhunting madness.
