The possibilities are definitely there but you have to work hard to get them.
In the first few years it's easy to move up the ranks, but it slows down a bit after a few years. It's still relatively easy to get to manager or partner in under 10/15 years or so.
I do not know. Some people seem to be able to move up very quickly whereas others seem to take a while. I will try to make the most of the opportunities I am and will be given, and hopefully in a couple of years time I can confirm that it's easy if you put in the work.
Unaware at this stage of my career
