I think a lot of companies arbitrarily inflate/misuse/invent titles for their own purpose. I saw EngiineeringLadders[1] here on HN that I can appreciate for it's attempt to quantify things a little more clearly.
I was the Manager of Information Systems at my old company. So, the computer guy who kept the exchange server running, set up workstations, basically the entire IT department.
Our sales people were Senior Account Executives, because nobody would talk to sales people.
Title inflation is real.
