As long as you're gainfully employed and can prove it (E.g. EPF, bank statements, pay slips), shouldn't be much of a problem

as per what I've been through, there's a catch. you have to transfer you primary bank account (esp account which you get your monthly pay) to bank islam, which I can say somehow I regret of doing so, in view the s*** level of the internet banking they are offering right now.

anyhow, their rate is quite attractive. I managed to get RM10k loan for 3 years with monthly deductions of RM301 per month

Packaged = Private Sector but Panel Bank for your company.
Non-packaged = Private Sector.

You can check with them whether your company classified as panel or otherwise.
However, you need to take into consideration like 2 months of advance payment will be deducted from the loan. Need to transfer salary to their bank, stamp duty, wakalah fees and etc.

But still, non-packaged also the interest quite low.
