Let's Get Ready interview questions

Very disrespectful and rude experience! I was invited for an interview. The night before my scheduled interview, I received an email asking to reschedule due to emergency travel. Then, they proceeded to reschedule me. I selected a new time and date with a staff member. I later received another cancelation and a message from their recruiting email saying they regret to inform me that my qualifications (6+ years in nonprofit) don’t match what they are looking for. They wasted my time and were very unprofessional. All of this for a job that pays $50k a year and requires 2 years of work experience. Unbelievable.
