No, CSAM at IIIT Delhi is definitely not worth it. Here is a detailed review of the program as shared by a friend
All in all, the CSAM branch of IIIT Delhi isn't a good choice if you are primarily interested in placements. It is futile to study such high-level Math if only your knowledge of Data Structures, OS, DBMS, etc. will be considered during placements. CSAM should be considered only if you are interested in research in applied math.
