Avantages
There is not enough work so plenty of spare time to explore new technologies. Good work-life balance Not much technology know how required, as it is a repetitive work usually its support. No work pressure, extremely relaxed environment Might get to travel for couple of weeks to Glasgow It is advisable to join if you need relaxed job with not much work pressure and do a part time job, however this is not a company to be with for long time. The interview is not justified with the kind of routine work, so make sure you prepare good for interview.
Inconvénients
All the important tasks are performed at headquarters, so other offices do not have any technological updates. There is not enough of work, most of the work is support(No development). Nothing new to learn in terms of technology Very limited domain knowledge is shared with other offices except for headquarters. No trust on employees at other offices, and everything works as decided by upper management. No HR policies (specially for US and Singapore). If you need job satisfaction in terms of work quality and working environment(management)/ policies this might not be the right option.
