Massage Envy interview questions

I was called 3 weeks after applying. I went in and they asked me a few different questions regarding why I wanted to work there and why I wanted to be an esthetician. They also asked me for my availability. I specifically applied for part time due to my other job and needed it to fit into my already-made schedule, which they initially told me would be no problem. They told me they really liked me and even went ahead and set up a practical. Then, 30 minutes later they call and say the general manager actually specifically needs someone to work the worst hours: All Friday nights, all Saturday nights, and all day Sunday. This completely went around the availability I told them (I already work weekends at my other job) and they couldn't work with me at all, so I had to decline.
