If you're applying for the grad scheme (joining as an E1), the fastest you can make it to manager is in your D5 year (ie 5th year).As for Director it's not as straight forward - one of the biggest jumps is from senior manager to director, as it is effectively a screening process for partners, so they expect you to have performed well and had 'outside the box' experiences (international secondment). I'd concentrate on manager level first!
