Short term

Dear Parvati,
There is no shortcut to success!
You may pursue diploma courses from FTII, Pune to get the best knowledge about film and television industry and will also open various career prospects for you.

You may go for GIS, Robotics, SAS, Networking, Cloud computing, DBA.

Dear Abhay,

There are few institutes who offer job on joining the course like NIIT has tie up with ICICI bank
The course is some diploma for 6 months and it costs approx 90000/- and you get placed in ICICI bank post senior officer on first day of joining and pay is 220000/- per annum
(this is inquired in mumbai malad NIIT branch) and it may differ from place to place
but dont go for it since these jobs are contractual and you may have to leave after 2-3 years
You have experience so you can try many places for new job
Even you can go for CFP there is no guarantee but it adds value to your education

A whole range of certificate & diploma courses is available in both online and offline mode in many management institutes. Few of them are in finance/ taxation/ banking/retail /supply management etc. Share your interest to know further.

There are too many courses. Please let me know the subject of your interest.

You can go for Certified financial planner by icfpi
or Certified Credit research analyst by CARE
Both are good courses but scope may depend upon Jobs available
These both can be completed in 5- 8 months depending upon your strength

Refer courses from NCFM, Edx or NIBM.

I would recommend IHM Mumbai.visit http://www.ihmctan.edu/programs.html
