I applied in-person. I interviewed at Lehigh Valley Zoo
Interview
They asked very basic questions about yourself and goals. The interview probably took about ten to twenty minutes but overall, it was not the hardest interview I had. They were laid back.
I applied through an employee referral. The process took 1+ week. I interviewed at Lehigh Valley Zoo (Schnecksville, PA) in Mar 2013
Interview
The interview is pretty basic and you should be able to answer all the questions. There will be either one or two managers present and they'll most likely be your new direct supervisor if hired. You should get about 14 easy straight forward questions just so they can see your intellect capabilities really.
