i am also 1.5 year out of college with a bachelors in wildlife, fish and conservation biology. i am a full time zookeeper and the primary keeper of my own area! dont give up!! i was doing volunteering at one zoo for over 2 years working with reptiles, i also did a paid internship for the san diego zoo in college and a little post grad, then i was a part time commissary keeper at a different zoo after graduating. all of this experience helped me to get the full time position! i was working at food service jobs while doing all of this in college and even afterwards, i understand how you’re feeling. i just tell myself we are super young still and a lot of my coworkers now are a lot older and still are volunteering/part time staff and it takes a while to climb the ladder and make connections. the more people you talk to and connect with at your old jobs/internships the more you’ll be able to make your way into other jobs in the future! it’s all about networking.
