Job Interview Questions: What's the most likely chances I'll get to reschedule this job interview?

I have a job interview today at an animal shelter, but I think I'm going to have to call in to reschedule (if they let me) cause I have mandatory dance practice the same time my interview starts. My dance teacher told us if anyone misses this practice, they will be ask to leave permanently and not return.

Job Interview - 4 Ways to See Yourself as Job Interviewers Do

• Sorry, but if I was an employer there is no way I'd even considering employing someone who prioritises dance practice over work. To ask to reschedule this for this reason is unprofessional and shows a lack of commitment.
  I understand why you want to reschedule it but in all honesty you're going to have to decide how much you want the job, and which of the two means more to you. Because virtually no employer will employ someone who phones up and says "can we reschedule the interview I knew I was having and knew it clashed with my dance practice but on the day of the interview I'm ringing it to change so I can go dancing instead" now are they?
