Applying for positions after graduation.

[nevergiveup2016]

Hello so soon I will be able to start applying for new grad positions. There is one area I particularly want to work in. However I currently work as a CNA in a hospital. They have told me numerous times you have a job if you want it. But thats the thing.... I don't really want it. How do I say nicely "I'm waiting to hear back from other positions".. without giving them the wrong memo. I don't want to throw away a job I can have for a job I may never get... A lot of my instructors keep telling me you'll get plenty of offers never think that one job is all you'll ever be offered..
