How are the career growth opportunities on the Engineering team at JPMorgan Chase & Co?

In the engineering department they claim to offer everyone an opportunity to grow vertically and or horizontally. Unfortunately this never seems to be the case. However, the last three employees that left JPMorgan all received emails from upper management offering new job titles and a choice of what project or team they wished to be on. Basically you have to resign for JPMorgan to offer you a growth opportunity.
