CBRE Associate Accountant interview questions

I met CBRE at a college fair. They asked for my resume and then called me about a week later. I did not do any follow up with them after I gave them my resume, they contacted me first. I talked with a manager and she asked me a few typical questions that had nothing to do with accounting. She set up my interview. I had one interview with them in which I was interviewed by two accounting managers. They were very nice and personable people. They asked me a long list of questions and we had a great discussion about them. I then had three tests I had to take, accounting, spelling, and excel. They were very easy. After this I waited about 3 weeks before they made me an offer. I still have not accepted or declined. They are only giving me 48 hours to make my decision.
