Bizzabo Customer Service Representative interview questions

I had three interviews, and they offered me the job and later rescinded the offer because I couldn't drop everything and come to New York right away for training..They even agreed to the date I would visit New York for training and then changed their mind. I put in a resignation letter with my previous employer and almost ended up with no income source. It was very unprofessional. They asked to speak with me further about their decision, and I declined due to their lack of integrity in handling the interview process and offer of employment. I was afraid of job stability.
