which sorority?

also does everyone who rushes get a bid or is it more selective?

Recruitment and Greek life in GW is much more relaxed than in other schools. If you are considering recruitment, you should just go for it. Its an amazing experience. When you sign up you are assigned to a small group that has two recruitment counselors who are currently sisters. Any questions or concerns that you may have, they'll be able to answer!

Also, you could consider a community service sorority/fraternity like ESA or APO. The rush for alt greeks such as those tends to be less intense.

Okay so here's the deal go through with rush your freshman year, you will probably get a bid. Just try it out, if it's not your thing, drop out, but do it your freshman year because rush sophomore year is significantly more difficult. No matter what anyone tells you, getting a bid as sophomore is much much much more difficult, and you will regret not trying it freshman year. Every sorority is different, I'm sure you will find a sorority that fits your personality and goals, just go into recruitment with an open mind.
