Treat each rotation like a job interview which means you should be aiming to impress your preceptors, not necessarily with clinical knowledge, but with work ethic, professionalism and the enthusiastic desire to learn.
Ask each and every preceptor to be a reference for when you apply to jobs in the future so that you have a list of references to choose from. You can then choose which reference is most relevant to the job you are applying to, and choose references that you think will provide a strong and positive review of you.
A great way to prepare for interviews is to reflect on yourself, your prior experiences and how they make you a suitable candidate for the position. You could prepare answers word for word for many common questions, but it will not come across as genuine, and you may encounter questions you have not prepared for.
Apply to a wide spectrum of jobs to not only get practice interviewing, but there’s a chance that a speciality you aren’t necessarily interested in just happens to have the exact work environment and location you’re looking for which may be more important to you.
Speaking of, determine what you value most in a job. For me, it was the people I was working, the environment I was working in, and the abidance of opportunities to learn.
Keep in mind that in every interview, you are also interviewing the employer; ask about aspects of the job that are important to you and ensure that the job aligns with what you’re searching for.
