It doesn't have to be a big company. More important than what company you were in is what you did there. If you started your own company then sold it off for millions and millions, you'll probably be seen in a better light than "yet another consultant", since your results really show how capable you are.

If you want to go to a small company, focus on the "潜力公司", both for your own career, and from a resume standpoint.
