It really depends what role you are in. It also depends on the structure of the company. If most people are 'stayers', to have career progression you'll have to leave the company one day. This is also part of the reason why people job-hop. Don't think about career progression within a company, until you are in the company. Because that is when you'll see what kind of age groups are the majority in the company, and by then you can judge how you'll progress.
