I first received an email from a recruiter telling me to give available times and days for a phone screen interview. After that I had two follow up interviews with the company's associates.

Went through a presentation at first, describing the job position. Then answered basic questions, like tell me about yourself and how you feel working with animals. Good to know that you work a lot of weekends and some holidays, like New Years, Christmas, Thanksgiving, etc... Also good chance you need to have some late nights.
