My wife and I were invited for a second interview to their office in Cincinnati, per our conversation before interview they agreed to pay for our travel expenses, including airfare, car rental for two, which was nearly $1000, although it was the peak of CoronaVirus pandemic in August, we travelled a three hours flight from Texas. The interview was successful and we had a nice stay there but they did not give me the offer I had expected (as we discussed before the interview) , and after couple of weeks we decided not to accept it , during this period they delayed the payment till they hear from us, and after we told them about our decision they refused to pay us the travel cost we agreed on (not professional at all)
