Hi blackcaps,
May be it is happen for small level companies, in MNC I guess they strictly follow rules and regulations, they have to submit the selected Candidates list to Top level Management and while they place the candidate in project they will arrange client interviews at that time they will defiantly share your details to client, So as per my knowledge in MNC it is some what difficult.
Before switching to Backdoor option, rethink once again, because it is too risk.. there is no guarantee for your money. It is like head & tail method, rather than pay money in single step, ask them to deduct from your monthly salary. May be they show you offer, after that company found that you are fake then what you can do? that time it will create big problem, and your money also not come back. So, rather than wasting time to go like this, my suggestion is learn any new technologies which is available in present market. and highlight the same in your Resume, that will give you good impact to your profile. Try this, if you still not satisfied then final decision is upto you.
