Got offer from 2 Organization.

Hi everyone, As I was searching for new roles and opportunity in many organizations I have finally received 2 offers / opportunities from Decathlon and Zomato. I'm currently in Bajaj Electricals Ltd (Sales Profile). YoE 1 yr and 3 months. Serving notice period (September is my last month). Current CTC - 6 lpa. I'm more interested in Operations / SCM profile and have been applying for the same but no luck even in entry level positions. As I have been applying for jobs like a robot on daily basis for the past 2 months, I have finally got 2 job offers. 1. Decathlon: Job Role: OSL Salary: 28k per month Location: Pune (Home Location) 2. Zomato: Job Profile: Customer Experience Associate (ZAAP program) Salary: 5 LPA CTC Location: Gurugram (Not bad huh) Now both organizations are good and both are offering a bit low in terms of Salary (especially Decathlon) but for me Salary is less important and professional growth is more important. I want you guys honest suggestions as to which one will be more better and how it will help me in professional growth in operations/scm. Thank you.
