Hi Anchal.. SAP is good option to start with and already too much HOT in the market.. But no institute can promise you a job.. your capabilities and expertise can grant you so. Better to start with you can go for local institutes to get cheap training and make your expertise in at least 1 module and then try applying for the job

Hi Anchal,
It's good that you are trying to figure out some logical path to resolve the issue. However, dive into SAP field after knowing its nature of work, and if you can do that well.
As for the training, SAP has authorised training centeres across all major cities of India. A consolidated list of which can be found on the SAP training official website.
However, keep in mind that SAP certification is very expensive, it costs around 3-5 for different modules. Also, SAP certifications are recommended more for guys with some experience rather than freshers. The cerificate training is of the duration of 15-25 days normally, co you need to have a sound plan and strong focus to clear it. It would be tougher than any of your Btech exams. I am not trying to scare you, but keep such aspects and cost in mind.
Also, major MNC's are gearing up for hiring freshers, both form 2013 and 2012 batch. IBM has begun freshers recruiting last week and more MNC's are expected to follow. So gear up your basics of aptitude and engineering.
All the best ahead.
