That's why I've been saying these to people, never trust what the HR tell you at the interview, particularly with regards to upgrade time, they might say 3 years, but the reality is it could be over 7 years, depending on which fleet you are on obviously, and they won't bother to tell you. It is one of the tricks they use to lure you in, especially for the new TA team where most of them have a strong recruitment agency background. That's why things have moved so quick comparing to the previous TA team.
