I want to study Master degree in GBSB. Can you please tell me, do they really provide employment and other things?

They don’t “give” you a job, but they do have career services and most master’s grads seem to find something within a year if they’re proactive. Their own reports claim around 80–90% employment within 12 months, plus lots of internships that can turn into full‑time offers.

I you go, assume you’ll get useful support and a decent brand, but you still need to network and apply a lot.
