Pros
The fact is, at FDM you're going to get a job at one of their clients. That is the ONLY pro this place offers you. If you, for whatever reason, don't feel like you can apply for a similar role at one of these clients, then FDM can help you achieve that. Oh, and the salary is comparatively higher than most graduate trainee jobs available in Hong kong.
Cons
Note that you do not get any say in what client you are placed into. Remember this very carefully, that it is in their incentive to place you WHEREVER AND HOWEVER THEY CAN. They don't really care if you don't like the job or if its a dead end for your career. If you fit the client's requirements and get the nod from the client, then FDM will place you there, whatever your misgivings. Another thing to note is that while FDM claims they will train you, the reality is eight to twelve weeks of training isn't enough to homogenize a whole group of people. Trainees have their own skills, strength and weaknesses and job experiences, and those juicy placements at the big banks (Morgan Stanley is a favorite) that they dangle before prospective trainees? Its for people who could've gotten into these places anyhow by themselves but somehow ended up in FDM's court. The rest of you, feel free to dig through the client list at FDM.
