Hi Surman,
Starting with my opinion..Its right move for sure. Most of professionals who are coming on HANA track are experinced only. And in fact it would be an added adantage to have DB knowledge. Now You can either go for HANA as
-> Appliaction Consultant (Implementation & Modeling - HA100, HA300, HA350 & HA900) or
-> BW on SAP HANA (BW362)
Both are having good scope, but for secodn option You need to have good knowledge of Data Modeling & basics of SAP BW. When You do Certification, Those guys help to get interview calls. As there is a good variation in packges for HANA professionals so I would not comments on figures. You can get more information on SAP Training Partners at Training Locations
Please do not rely on promises, local institutes do for job assurance.
Warm Regards,
NS
