Top Law Schools

I am a rising 3L at Fordham law and I would like to be able to work in Chicago big law after I graduate and I am wondering where I would go about looking for firms in Chicago that are hiring first year associates? Thanks for any answers!

Op here, still wondering if anyone has any input? I understand it is tough to get big law as a 3L but I would just like to know where to even start looking? Do I just do what 2 Ls do and mass mail?
