As an engine tech for a diesel truck service center, I can seriously sympathize with where young chinese people are coming from. excessive overtime, even paid , can turn you into a miserable zombie pretty fast. somewhat quickly after my apprenticeship I was gifted quite a bit of nonsense overtime from the old timers. rotor turns, oil changes, timing, valve clearance, etc... were all heaped up on me until I was spendi…
Long of it is: it wasn't worth it. Most of the time was spent fixing/implementing things that were poorly spec'd out or the "spec" was verbally (and poorly) communicated so often developer & manager disagreed on what was previously understood. But, hey, time to market, and all...
Last half of the project I told my manager to fuck off if he came to me with a verbal change to the spec (and I had permission from his manager to do so because I'd voiced the complaints and we had delivery date slippage). Put spec changes in writing, an email at least, so we'd have a written record of what was expected. That helped - a little.
