Ectc for 6.3yoe in Deloitte USI

I have total of 6.3 yoe and I have cleared all technical rounds in Deloitte USI. Initially I have applied for senior consultant role but they have updated it to consultant-data analyst My interview performance was very excellent I can give 98/100 I had taken many interviews lost a few initially gained much confidence else I wouldn't be able to give mark Now the question is what could be ectc How much can I ask I have offer with 34lpa from Indian mnc But I'm much interested into DUSI What can I do now Do they change band to match ectc as it's 6.3yoe can they change it to senior consultant or how it goes or do they drop in between due to budget...

Please give valuable suggestions and insights on this and help me to get better offer and how to negotiate to get better
