Round out your skillset.
There are hundreds of online courses available from Oxford, Harvard ManageMentor and others through iTunes or their own subscription service. Most of these take just a few hours to complete and can help round out any knowledge gaps on your resume before an interview. Look at keywords in the job posting and search for online courses that address them. Then complete the courses and talk about the training if the topic comes up. This will show that you are willing to go the extra mile, educate yourself on topics important to your position, and open to continuing education once you’re on the job.
