My condescending male coworker won’t stop telling me what to do
I love working for my manager and my team, but one of my newly hired coworkers has recently been giving me tons of unsolicited feedback. He'll make comments on everything from an article I wrote to my LinkedIn profile (I didn't know someone could have too many connections). While I appreciate critiques on my work, his feedback is going a little too far and is always very condescending. My manager seems to really like this new hire and doesn't seem to notice this behavior. Any advice on how to (politely) get this coworker to stand down?
