My wife was stressed out the other year because what was formerly a title system at her BigCo of A -> B -> C ->D got fragmented even further.
They added some system of "well to get from C to D, there is now C1->C2->C3->C4, and we've classified you as a C3, congrats".
Of course this week out of the blue her boss calls her with the "great news" that she's been "put up for promotion process for C4, but no guarantees"..
Anyway few understand this but even in these types of roles, the compensation bands are very very wide, with overlaps, and differ across departments. So just ask for money over title until your title limits their ability to give you money. You can't eat title.
