They could have completed a job quest at 60 for DRK, RDM, AST, as an example - ones that start as a job and not as a class.
This is very true, though the OP mentions over and over again how the accused player has no jobs what so ever. If this true then the likelihood of becoming a mentor is slim. Unless of course they bought jobs jump books to instantly have those job quests finished.
