When reading your message I am thinking my early career after graduation. I was a trainee and involved in different projects in different offices. The company had a long history, was well-established but not best in class. I felt, at that time, that my experiences were piece-meal and not solid enough too boost my career. Plus the low salary too.But several years later when I was looking for other opportunities outside, I found that my experiences and skillsets at that time were extremely valuable. Not many people had the wide range of roles, knowledge and skills as established in such a short time as I did, which was across commercial, operations, systems and process managememt areas. I also found, frequently, that my experiences before could be applied on my existing work. Financially, such experiences also gave me a significant (6-fold) increase on salary level.I think what you should do is to review projects you have involved and find out what achievements and transferable skillsets you have built up. Then make a good cv to sell yourself.
