Articles include the problems of being obsolete at age 30, and a comment that Huawei is "cleaning up" the staff over 34. There's an online course on how to become an embedded systems developer by writing your own RTOS, and what questions Huawei asks in interviews. Somebody wants help with their square wave generator, which is producing a poor waveform. Somebody else wants to know how to drive a 12V brushless DC motor 300mA 2000 RPM. Nobody posted a useful answer, which is disappointing.

All in Mandarin, of course, but that's what Google Translate is for.
