May I know currently in what industry are u?

Just jump to o&g. either going to the operator or the vendor or consultant, its up to you.
just a gentle reminder, o&g field measures you with your experience. eventhough you have 1.5yrs of exp,
chances are you will be paid as a freshie level. those operator companies (shell, petronas, exxonmobil, kpoc) pay more than the vendor and consultant (obviously).
if you're not that lucky, you can still enter vendor (like transformers - abb, or DCS - honeywell, emerson, yokogawa) or consultant (technip, aker solution, ranhil worleyparson) but the pay is just slightly above the average. normally the OT & onshore/offshore allowance in o&g field are highly paid. and its a trend that people just work for contract position, and not permanent. once you've entered o&g, you'll know. im in vendor company. OT is arnd rm20 per hour. basic is just 2.8k. onshore allowance rm60. offshore allowance rm180. mileage rm0.70. age - same as yours, but im in electrical line. later after a few years (normally pple set 2 years) you can jump to your client company (operators)
