Afficiency interview questions

The first interview was rescheduled multiple times within the span of a couple of weeks, with the interviewer even letting me know that she didn't even have time for the interview at the outset. Immediately, I was told that the job was not a 9-5, which is not accurately reflected by the pay-scale or the job description. After no response for a few weeks, I finally interviewed with the CFO, although I was told I would be interviewing with both the CFO and CEO. (Again, a clear instance of disorganization and unprofessionalism.) Afterwards, I interviewed with the CEO. Counterintuitively, they set up yet another round, with the CIO. There was no organization or instruction about the interview process; it was very haphazard and seemingly never-ending. After giving me a verbal offer and promising a written one by the end of day, I got a written offer later than the promised deadline. After signing their forms and the offer, they rescinded the offer in a very cold and unprofessional manner, only a day before the start date. The firm's behavior in this interviewing and decision-making process reflects very poorly upon the standards of the company and bodes terribly for their goal of scaling. I was told that 10 of almost 40 people left in the past year, and it is now apparent why.
