Anyway professional qualification is better compared to masters if you want to do post graduate studies (in europe this is the main trend compared to Asia). It is best to seek out those that entitled you a title like England is "Chartered" while US is "Certitifed".

It depends whether you want to specialise more into your are of expertise or diversify into another branch of knowledge.
I don't know much about MFE but i know about the other 2.

MBA graduates hold the highest unemployment rate in MYS (more than hundred thousand are jobless). MBA is not meant for you to study & find a job. Its rather you find a job, the the boss may evaluate whether you are fit for managerial capacity & sent you accordingly. Or you wish to open up your own biz & wish to know the handling of biz more thoroughly. Deemed one of the least important professional qualifcation.

CFA on the contrary is highly rated as the exam is quite difficult & the lowest requirement is that only a degree holder can apply. Its a US course.
Common misconception is that due to financial crisis many are laid off especially in finance line. But that applied to disposable workers without any core skills or qualification. CFA holder are quite strong & quite recession proof. You can read it in internet or international papers about CFA credibility.

I have several relatives & friends who hold finance degree from Australia while some in singapore. It depends whether you want to remain in banking line as CFA can really help you. If you think finance should be more generalised why not coupled it with accounting ?

Other courses like CIMA, ACCA & CPA is quite recommended & also recession proof professions where job entrenchment is quite unheard of for those who hold these. My current classmate in professional qualification class holds a finance degree from australia & his reasoning of post graduate skills is to multi-skilled instead of specialisation.

It depends on what you want & plan to be in future. Anyway with degree alone you will find it quite hard to compete with those whom possessed professional qualification unless you really aced that interview or you knew somebody in the organisation

Some of my uncles who has been engineer claimed they cannot diversify easily from their engineering post as engineering is quite specialised in nature compared to others. One remain to become chief engineer while the other sucessfully manage to enter into consultant capacity.
MBA is not bad but most people pursue it on their own without realising the benefit to their occupation. Normally the employer who will assess their successor then they will pick the staff to undergo MBA. Not the other way around. One of my post graduate studies includes a portion about MBA called business analysis. It all depends on your logical skill compared to learning.

They can ask like what is the key criteria to open up an european restaurant in exam ? If you learn MBA you can quote models & frameworks but without one you can still use your logic & experience to deduce. Thats why fresh graduate with MBA are not highly regarded as they lack experience.

CFA is considered master or some kind but definitely higher than degree. You won't hear much of CFA graduates in MYS since its a US qualification & there is not many centre in MYS teaching it. Many can boast themselves as financier (just have to take up a short stint license) but CFA is the another rung after it. However CFA recognition is higher in US compared to other countries.

But CFA requires heavy application of accounting in level 1 & 2 & financial advisory later on level 3. Although engineering + finance may be a good synergy but learning something new & completely different may be difficult. Professional qualification is not like degree / master they practice "exam-based approach". They only allow you to take exam but you need to find your own tuition provider & study on your own. Thats why these courses has less appeal to asian students compared to the more care-free westerners.

cfa is very specialised....i suggest you shud not take it. if u do want to take an mba, (assuming u qualify) the mba awarded by manchester uni from sunway could be good for u since you're in engineering...
