Need guidance and clarity regarding Business Analyst roles

I'm currently in my final year of BTech and planning about preparing myself for Business Analyst roles.

Please help me and guide me in clearing a few of my doubts:

1. What is the growth curve of Business Analyst roles? Is there a steep curve like those SDEs in PBCs or is it a shallow curve in terms of salary and designation?

2. How good is the exit? I mean to ask that suppose an SDE resigns and plans to start his own software company(where he can apply all his technical experience). So similarly what type of exit can a BA get?

3. What kind of work life balance is there? Pls suggest some companies too where the pay and work life balance is good.

4. Do we get to work remotely as a BA just like SDEs?
