Wow. I definitely wasn't expecting this. After telling them yesterday about my other job offer, Chicago informed me that they gave my job to someone internally. Yep. They gave me a tentative offer, said the job was mine or no ones and that there were just a few formalities to go through, and then gave the job to someone else.
So yep, I'm staying here in Boston with the other job. I'm so angry. I should be excited to have a new job, but I'm so disappointed and pissed with Chicago.
