If you read through the thread you'll get an idea about the working environment. You'll enjoy working in Malaysia. I wish I could work in Malaysia but then again, I will not be earning expat salary like what I am earning now.

Be patient and follow all the necessary process. The visa processing will take time as Petronas will need the necessary approvals from the the relevant ministries. Do not tender your resignation until everything is finalized.

do you think my chance to get the job at petronas is bigger if i have my industrial training there?

oh, I would like to share my experience here.

around mid of december 2012, I went for SI (I'm a PETRONAS scholar)
SI result was out around 31st January 2013 (Gotta wait till our final examination result came out)
a week later, 7th February (if Im not mistaken) received a phone call for placement from PETRONAS. (like chitchat session or something)
I was told that the medical check up letter will be emailed after chinese new year.
Due to some graduation problem I received the medical check up letter a bit late than as told. But not that late la. I received it last Monday. (On previous Friday they called me to inform on the kelewatan)

And yesterday I went to PUSRAWI, do all the medical checkup and stuff. At around 3 I sent the result to HRM at KLCC.
And early this morning, I received the offer letter through email (so fast meh! I was so surprised, (iyalah, after reading through this thread))

Oh the conclusion is, I guess HR PETRONAS is not that slow.
Plus if I'm not mistaken, different OPU has their own different HR.

I'll be reporting for duty this coming 1st, March.

and my PIPE will start on 18th March.

p/s:  pretty excited to start working at PETRONAS. I'm looking for any kind of guidances and experiences from all of you here.    Thank you!
