Regarding Placements at ISI Kolkata

Hi everyone, I’m an aspirant trying to understand how placement interviews usually work at ISI as DSA or Programming might not be only thing there unlike IITs. So,

For seniors or alumni who went through placements, could you share your experience?

What kinds of questions were asked in interviews for tech, quant, analytics, or BFSI roles? Can u please elaborate it individually !!

Which subjects were most important (DSA, probability, statistics, ML etc.)?

Were interviews more coding-focused, math/statistics-focused, or puzzle/problem-solving based?

It would really help people prepare better since there's only a month or two gap after entering masters. Thanks!
