Salary expectation and hierarchy, any Tata communication folks here??

Hello guys, I'm interviewing for an Assistant Manager role in marketing at Tata Communication Limited for the Mumbai location.

I would appreciate it if someone could give me some leads on the position hierarchy in the TCL and a salary for the assistant manager.

Urgent as I need to have an HR meeting for salary negotiation.

Background info with 1.8 years of experience and I hold a bachelor's degree (BCA)
