The vast majority of titles in tech confer more prestige than deserved, because there's no downside to a company handing them out like candy. I don't look at it as a portability issue, the incentive isn't to be accurate to begin with. Inflated seniority is just a perk they can offer that doesn't cost them any money, so everyone offers it. Titles across the industry are meaningless unless you're calibrated to that company's levels.
