Don't worry, Tencent is just as much souless and bigcorp than facebook. I would say even more comparing what my friends have said about working at tencent vs facebook.
Tencent is a pretty bad place to work at, how they constantly discarded their work projects, have typical chinese work hours where people sleep under their desk despite being huge co and said other friends who worked there had a bad time. They did like their immediate co-workers although.
While friends and coworkers who work(ed) at facebook have had a much better time, with far more perks, interesting projects work not thrown away and a much better work life balance.
