I am going to answer your question based on the idea that what you mean by job category is actually level. Junior, Associate, Senior etc. This is incredibly specific to the company you are working for and the industry you are working in. An Associate Director title in one organization may be a Senior Lead in another. You need to research this for the companies you are applying to using a professional network or LinkedIn (or the like).
As previously mentioned, if you went from what was a clearly a more senior position to a position that is junior, in the same company and industry with the same nomenclature, that might very well be concerning to a future employer. It is also your history and you will need to speak to it.
If you switched companies or industries and the titling is inconsistent, that is worth narrating in your resume/cover letter, but is not a detriment.
You want to represent yourself clearly and with in a way that shows the recruiter you are the best person for the job. Have a look at your resume and online professional profiles and see if that is the impression you get. If you're not sure, ask a trusted advisor or friend to look at what you are presenting for their overall impression. Taking this hard look at how the world sees your work experience will only make you better prepared!
Best of luck!
