Just caught up on your job search. I say, take any zoo or animal related job you can to get your foot in there.
I have read that it’s good to ask what you can improve on if you don’t get through an interview. Now years ago I did actually have to hire people periodically, so I was thinking about that advice and whether it is practical. I don’t think it is. Because if the hiring people tell you the truth the are leaving themselves liable.
If you don’t get something, I would make a note or diagram of it and put next to it what your gut instinct of where you didn’t measure up was. Like if you got a sense that they were surprised when they saw you in person, or if they were excited and then they asked about a certain type of experience and didn’t seem as excited about your answer. Then you could look at how to tweak things.
I also wanted to point out that your relationship with your husband looks to me like an indication of your greatest strength-like you know they always ask that. People are usually like, “I’m a hard worker...” (sure...) It sounds to me like YOU are DEVOTED. Whatever you are committed to, a job, an animal, a person, you pour yourself into 100%, and don’t stop until it’s taken care of. I would highlight that strength in interviews.
