I respectfully disagree about Bangalore / Gurgaon office. The time difference between west coast and Bangalore is 13.5hrs now (or 12.5hrs for ~8 months). That makes it very hard to have even meetings, let alone meaningful collaboration. Even 7am in SF means its 8:30pm in Bangalore (or 7:30am in Bangalore means its 6pm in SF). With east coast, time difference is still 9.5hrs vs 10.5 hrs - only slightly better.
Source: first hand experience working with Indian colleagues while in SF; working with US colleagues while in India; observing hundreds of colleagues over the years, vast majority of whom arrive at work ~8:30-9:30 and leave ~5:30-6:30; frustrations of those having to attend late night / early morning meetings and how that affects personal lives.
As a remote worker based in Thailand had worked with guys in CA (14 hrs difference) for almost 2 years. It is true that life style and physical body got seriously affected.
My regular meeting time is 1-2am, paring with designers at 5-6am sometimes. Always not sure when to sleep during daylight, eating time messed up. Biological cells never get used to it. Anyway, I love my team.
