not sure if everybody who commented NO to bnm been working there before?

i would say its not easy to get a job in bnm. bnm have all the benefits which kp does not provide.

kp only the brand. if u choose kp, u should consider pwc or ey then

If BNM is offering you a job in its statistics department, and you are being offered an auditor or tax position in KPMG/EY, there is no direct relation between both roles and they lead to different careers. 

I think the first question you need to answer is what do you want to do with your career and what you want to be in 5yr, 10 yrs time.  Then choose the job that takes you there.

I would say if you are not sure what you want to do, you should join an audit firm if your intention is to be an accountant or manager in the future.  They will offer you experience that will improve your market value in the next 3-5 years if you choose to join an MNC.  The experience is very generic in the sense that they teach you "how to do" things and keep you abreast with the changes in the profession.

If you join BNM, I am 80% sure the lifestyle is better (less stress, better hours, better benefits, and decent pay).  BNM does not limit your future entirely, depending on what you do.  But it could limit the industry your experience is relevant to.  Your experience will be a fair bit more specialised than what you would pick up at an accounting firm.  I don't foresee you joining a telco or manufacturing or O&G company in the future after years of service in BNM.  But if you like what you do, and BNM offers you the mobility to move around different departments, you could have a good future in the financial industry compliance teams.  You should speak to the BNM people and find out more about your progression structure and consider how that experience helps you in the future.

With all that being said, you are just entering the job market and this is not a life-and-death situation.  If you don't like what you do, there is nothing to stop you from changing jobs as its still early in your career.  You only lose out 1-2 years time in progression which isn't that big a deal in the long term.
