I'm currently looking for a new job after being made redundant and it's proving an absolute nightmare figuring out the level of position being advertised. We've got to the point in the UK where an 'executive' (historically a Board level title) can now be given to a call centre worker, a 'director' (again a senior level title often on the board) refers to the tea boy and a 'manager'/'engineer' title can be anything from a low level supervisor to a head of a global department. I know this is a little bit traditional, but there should be a standard global ranking system for job adverts that indicates the approximate pay grade.
I had a conversation with an acquaintance who works at a bank recently: "I got vice-president." "That's great!" "No it isn't, I'm the last on my team to get it." "... everyone on your team is a vice president?" "And three quarters of the whole department." I insist on calling myself a programmer, on the grounds that anyone who assumes I'm a peon to be ignored because of it is someone I'd rather someone else have to deal with.
