You can have the conversation but no use really. Do not put papers to get that conversation. you become black mark in company. If you have offer and put paper just move on

Yes they will not be able to match the exact expectation but wanted to understand if such conversation only happens when you put your papers or otherwise ?

No use… just get the new offer and move on

Yes that option is always there.
