I worked for NDI, with Dennis as my boss, for 6 months. I would never ever recommend working for him, although I wouldn't necessarily discourage anyone from working at NDI, as there are several branches in Chengdu. The work was easy, the physical work environment was comfortable, the staff were friendly and the administration (barring Dennis) were occasionally unreasonable, but generally minded their own business and let the staff see to theirs.

On the other hand, I wouldn't go out of my way to recommend it either. It all depends on what other options you've found.

Feel free to e-mail me if you have any questions about NDI, but note that I left their employ in August 2008, so my info's a little old.
