I joined at well over 30 at a time where supply far outstripped supply and RYR could take their pick. I have met many others who also fit this group.
There is no doubt in my mind that age is a factor that the airline takes into account in selection. As older pilots, especially as cadets, we are a higher training risk. That said, the fact the I, and others, exist in the organisation shows that you did not get passed over solely based on your years.
