Interesting perspective! As an engineer contemplating SG, I would love to hear your Singapore story - what did you find there, and what did you eventually do?
I found it was 98% companies like ^^ that. The companies I actually worked in were bad.
I found two companies that seemed more or less sane (ok, but neither blew me away). One of them was receptive to hiring me but I got a different offer before we worked things out which I took and regretted. The other deliberated for, I think, two months before giving me an offer. That was more or less the last straw.
I turned them down, returned to London after that and doubled my take home pay.
Not long after I returned I discovered that not one but both of these companies were acquihired by Google when they opened an office in SG. I had a good chuckle at that.
Yeah, I'd avoid it. There are pockets of good stuff as there are anywhere, but I think they're fewer and further between.
