Taking a gap year. Will apply for residency next year

Hi everyone! I decided to take a year off after finishing pharmacy school this May. I have a retail grad internship lined up and plan to work there for the next year as I prepare for boards. Any advice on what I can do to make myself competitive for residency applications next year? Is it truly harder to land a residency after being a year out? If anyone took a gap year, applied to residency, and got in a year later... any tips is much appreciated! Thanks in advance.
