I applied to the job on their site. I received a phone call the same day. Had phone screen with the guy for 30 minutes. 2 days later I received confirmation of a F2F interview for the following week. F2F took 2 hours with two people separately. I thought it went well, but I am still waiting to hear from them and it's been a couple weeks...

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.
