Your first professional experience is good and relevant. 市场调研咨询公司
You try to apply directly as a management consultant. For that, you should not wait for too long, as management consultancies like MBB typically hire graduates and young professionals, not people with a lot of experience. There are other consultancies, such as Booz Allen Hamilton who also hire industry experts with quite a bit of seniority. You could try to first get into the support staff of a management consultancy. They all have in-house market research departments. I know, because if they don't know any further, they come to my company Debrouillage Ltd. for help. We do especially company specific research (suppliers, competitors, customers), and less the entire markets. I have seen good people from the in-house research be promoted to management consultants. So this is a way to get a foot into the door.
