General Assembly is an awesome school for tech careers and has (or had) a lot of really cool and fun events. I really loved working here! It's located in Ponce City Market and super close to the Atlanta Beltline. I moved to Columbia recently but I know you will love it! They don't know that I am not coming back yet so apply soon!
A couple after hours locations open after midnight on Sunday: In East Atlanta Village, in the back parking lot there is a door covered in grafitti. This is the HUSHHH private membership event. All you need to do is sign a release, pay Annual membership dues of $5 and you are good to go!
