ABB IT interview questions

I talked to them at a showcase on campus. The hiring manager loved me to death that when I see them again at the Career fair on February , they let me skipped the whole line to put my name down for dinner. They wanted me to come work for them full time at Selmer or Morristown, Tennessee; flew me out for a tour on March discussed 3 positions and told me I should know the answer by late April which is already a long time. Didn’t hear anything from them, I checked in with the hiring manager, he said I’m still a top candidate, told me not to worry. Then few days later, he called me asked if I’m interested in an internship instead; I said no. Then a few days later, I called again, and the hiring manager told me that they had acquired a new company so they wouldn’t be able to extend any full-time offer. This company is a joke. They didn’t inform any of our students that they are on the verge of buying a new company and that hiring freeze might happen. They wasted my time and money. And it’s now almost July, i still haven’t got my reimbursement. HR keep asking me for banking information and all types of verification. I checked in with them 4 days ago about my money and still haven’t heard from them yet.
