Where do you go to keep your knowledge base on dental hygiene current?
Expect questions about what you've learned both on the job and off, both in structured learning environments and what you've basically picked up or embraced on your own. You should be prepared in advance to talk about how your credentials and training prepared you do be successful at this job. Step the interviewer through your motivations and goals for building your knowledge of the dental hygiene profession. If you have a portfolio that would support your claims and show hard evidence, this should help put the interviewer at ease that you possess the level of knowledge needed.
