Promotion possibilities are relatively regular, depending on your time and experience and performance in your current role. Because of the many site based assets the organisation has, as well as corporate locations, there are always opportunities available both inside and outside your area of expertise.
Depends on vacancies
If you work hard and produce successful projects and work I believe that there are many career prospects and avenues you can take. Networking is very important to make yourself known to the work community.
This company is more about lateral movements. At the top of the corporate ladder there are only a few roles available in my discipline. Much more likely to be moved into different commodities a number of times before being promoted (or into a different discipline completely!)
Based on performance Internal opportunities
Very easy but for only for some people
It is quite possible to move up within the company, so long as you are hardworking, a good coworker and show a drive to improve the business overall.
