Might also want to do a search on the forum. Chicago has been discussed a couple times in the last year or so. Your best bet if your serious about jobs in Chicago is to go to each and every airport and walk around each field and ask lots of questions. Don't just go to MDW, PWK and DPA either. You need to hit ARR, UGN, GYY etc. Its worth the legwork if for nothing else than the networking possibilities.
