So - on Thursday - the Cincinnati Zoo posted on their facebook page that they desperately needed Admissions staff to start immediately. I applied, got a call back the same day.
Had the phone interview today, went very well, I explained to the interviewer about all my pre-planned summer obligations (the two week practicum, honeymoon, my cousin's wedding) and he said that was not a problem at all and that he really appreciated me mentioning it before being hired though.
In-person interview is tomorrow at 4:00pm. He said I pretty much have the job - as long as everything goes well tomorrow (as in as long as i'm not a mean old slob, i guess?)
So..wish me luck. 
It sounds like a cool position. It is both selling tickets/ticket packages at the zoo - as well as scanning the tickets at the front gate.
