After mba what ca, cs, cma/icwa?

its depends upon u & and ur MBA specialization if finance ,u can do CA or CMA 

now comparing CA & CMA 

CA- if u want to get into(or interested in) Auditing , Taxtation , Accounting  , set up a Firm(practice) . Down side it takes 3-4 yrs hardcore dedication .

CMA - If u want to be into factory accounting/costing ,management accounting , indirect taxtation  , want a govt (PSU )job . downside CMAs dont enjoy CAs like social satus 

btw fields like  Finance ,MIS ,ERP , SAP,Internal auditing etc are open to both CA & CMA

i dunnu much abt CS

PS: Im am giving basic idea ! guys dont go pro on me :)
