I am a first time expat here in UAE, in Sharjah exactly. I arrived last July 2015, during the scorching summer
All is good so far, I never expected my expat life to be this good. My boss is a kind man, work is great, busy most of the time but no complaints. My colleagues are all of different nationalities, I have a good relationship with most of them. In my opinion you just need an open mind and an open heart so you can all work together nicely.
I've heard stories about Sharjah being boring and all.. It depends on one's lifestyle I believe. If you happen to live in Dubai before and transferred here in Sharjah (or Ajman) of course there lies the big difference. Dubai is Dubai, its glitzy, its alive and more options for entertainment. But for a beach bum like me, I can live with spending quiet afternoon by the beaches, have some shishaa and live a semi-hermit life
