Can I get a job in my field of interest with just my bachelor's degree in biolog

Entry-level lab or fieldwork is based upon the specific techniques you've learned in your courses more than the name of a degree specialty. A few fully professional positions - genetic counselor, environmental health specialist, clinical lab scientist (medical technologist), often require only a bachelor's degree but such positions also require internships or specialized training either during your bachelor's or thereafter. Teaching at the K-12 level also requires only a bachelor's degree, but there are quite a few unique requirements such as supervised teaching.
