Is this school desperate?

New to the field. I applied to a teacher position at a district and they emailed me literally 2 hours later asking to schedule for an interview on the 15th, but on the website the applications officially close on the 19th. They used plural and said "Interviews will be scheduled on the 15th" implying there are other people besides me interviewing if it matters. Is it normal for schools to schedule for interviews before the applications officially close and is this school potentially desperate for employees if they responded so quickly?
