How do I check my global rank, while in a lobby?

I"m somewhere around 800 in the world, for my global rank. I am a lvl 86 and do not know how to get to the "leaderboards or to anything that shows global ranks." someone tried to tell me before, but I never got to see what they said, the leader kicked me. So if anyone could tell me or explain to me how to find my global rank while in a lobby, I would appreciate it! Thank you.

 

Go into the steam overlay *tab+shift* then, click on *achievements*, go to *leaderboards*, click *xp* in the drop down, hit *show*, then it shows you in your friends ranks and tells you your global rank. To see yourself on the leaderboard, you would have to be in the top 200.

 

You should grind cause just first 200 are shown in leader board
