I can't speak to hiring practices now (I'm retired), but back in the day, putting your certification(s) on your CV would definitely be advantageous. If the job posting says “RHCE strongly desirable”, the non-technical person screening the applications would often put any that didn't say that in a different, lower-priority pile. Now of course the person who is actually going to be your boss is definitely more interested in your job history, education, and skill set than whether your CV is buzzword-compliant.

Whether that is worth it to you, given the cost of certification, is a different matter.
