See many data analytics courses are available. However it depends upon what kind of course you are looking for. I see many short term courses and also some are part of the undergraduation courses. IIT Delhi has the Data Analytics & Intelligence Research (DAIR). Check them here http://www.cse.iitd.ac.in/dair/. NPTEL offers free lectures and courses also. There is this one http://www1.iitkgp.ac.in/pgdba/ whoch is in collaboration between IIT Kharagpur, ISI Kolkata and IIM Kolkata. You can write to DAIR to ask for better guidance. However the institutes you talk about are also similar. I cant speculate how good they are. Placement prediction is always difficult as it always depends upon the candidate and his/her skill sets. I suggest you check the placement records and statistics of these institutes before you join
