Just like you must prepare information about the hiring company, you must attend your interview prepared to discuss what you will achieve if hired. Your first 30 days goals should align with the mission of the organization and your accountabilities in this nursing role.
Include personal and professional goals at work such as getting to know your peers, possibly joining a work-based social group to meet people, take advantage of Continuing Education Units (CEU) or even enroll in a course. Show the interviewer that you are prepared to invest in their organization, your new team, and in yourself.
