Career Decision: AT&T India vs Siemens Healthineers

I have two offers and need help deciding:

AT&T India – In-house data team, working on metadata projects.

Siemens Healthineers – Integration project, focused on system interoperability I guess.

My goal is to gain strong exposure and experience that can help me transition to a top product-based company in the future.

Which one do you think offers better growth and learning opportunities?

Appreciate any insights!
